The images in your peripheral vision are focused on the peripheral retina, and have vague, blurry edges and words that are not as clearly focused. It is classically described as having an anterior and posterior lamina and 3 named parts: the mesovarium, the mesosalpinx and the mesometrium. It takes oxygenated blood from the left ventricle through the aorta to all parts of the body, including some lung tissue (not air sac or alveolus) and returns the deoxygenated blood to the right atrium, through the systemic veins; the superior vena cava, the inferior vena cava, and the coronary sinus. The mediastinum is the partition within the thorax between the pleural cavities inferior to the thoracic inlet (first ribs) and above the diaphragm. The vagus (X) nerve is responsible for contributing to homeostatic control of the organs of the thoracic and upper abdominal cavities via autonomic neurons. Activities vary from requiring strength but little dexterity, such as carrying a heavy case or using a hammer, to those requiring selective grasp and dexterity, such as threading a needle. The evidence supported a hierarchical model with the emphasis on descending control from the cortex to the primitively organised spinal cord. For most of stance phase, the hip is in extension requiring full eccentric control and length of the hip flexors. Bone lengthening involves growth of the epiphyseal plate cartilage and its replacement by bone, which adds to the diaphysis. Just as maps are normally oriented with north at the top, the standard body "map," called anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward. The right and left crura are covered by the ischiocavernous muscles and the bulb of the penis is covered by the bulbospongiosus muscles. The human body is shown in anatomical position in an (a) anterior view and a (b) posterior view. Together, these factors may account for increased digoxin toxicity at low plasma K+ concentrations. Tracheloplasty repair of the cervix in which there is laceration or erosion (2) Desis Example: Epiphysiodesis repair of epiphysial separation due to injury. General causes include gonorrhoea, Trichomonas vaginalis, and Candida albicans (common in diabetes and pregnancy). Armchair or wheelchair seating must provide adequate support to maximise comfort and enhance postural and functional activity (Reid 2002). An intramuscular drug of proven efficacy, radiological improvement with decrease in radiological damage bore evidence of its disease-modifying capacity. Influencing the foot therapeutically after a stroke includes: provision of sensory information to the foot; stretch to the intrinsic muscles of the foot in order to selectively activate the foot; improving alignment at the talocrural joint; activation of gastrocnemius facilitates eccentric control of soleus; facilitation of ankle strategy. In addition, rectus femoris crosses the anterior aspect of the knee joint, and because the origin is proximal to the insertion, this muscle pulls the anterior leg toward the anterior thigh, thus causing knee extension. By third fetal month it stats is to descend and by the seventh month of fetal life it passes through the inguinal canal. The term "voluntary" suggests that there is a conscious decision to make a movement. The ground substance can vary from a watery fluid in blood, to a dense gel in cartilage, and even a mineralized matrix in bones. Examples of introduction procedures: Myelography a gas or a radiopaque liquid is injected into the subarachnoid space, usually in the lumbar area. Inferior to the clavicular notches, the first ribs also attach to the manubrium at the first costal notch (costal = rib). The paradigm of spinal fusion is based on the experience that painful diar- Degenerative Lumbar Spondylosis Chapter 20 571 throdial joints or joint deformities can be successfully treated by arthrodesis. Smooth muscle cells that are called precapillary sphincters guard the entrance to the capillary and determine into which capillary blood will flow. Painful soft-tissue conditions around the hip Trochanteric bursitis-This is a usually self-limiting inflammation of the bursa between the greater trochanter and fascia lata. Location Adductor hallucis is a third-layer intrinsic foot muscle, located on the plantar surface of the foot. The lateral side of the shaft forms a ridge called the interosseous border of the ulna.

Appropriate levels of compliance will be enhanced by ensuring the athlete has a clear understanding of the injury, its implications and treatment. The interdisciplinary team approach to moving from posture to posture can incorporate activation from distal key points. The corpus callosum is a broad band of fibres passing between corresponding cortical areas of the two hemispheres. The defining landmark of the medullary-spinal border is the pyramidal decussation, which is where most of the fibers in the corticospinal tract cross over to the opposite side of the brain. The Metacarpal Bones the palm of the hand contains five elongated metacarpal bones. Finally, because sartorius crosses the posterior aspect of the knee joint, this muscle flexes the knee. The middle layer of the eyeball, the choroid, contains a dark pigment to prevent the scattering of incoming light rays. Most medial of the cuneiform bones, located between the navicular and the 1st metatarsal bones. The sebaceous glands secrete an oil which lubricates the skin and keeps it soft and pliable and makes the hair glossy, 3. The hepatic artery carries oxygenated blood, whereas the portal system of veins carries blood that is rich in the end products of digestion. These include: practice (amount, variability, contextual interference [order of repetitions such as blocked or random]); part or whole task; augmented feedback (frequency, timing, bandwidth [level of performance to be reached before feedback provided]); mental practice; modelling; guidance; attentional focus (goal attainment) and contextual variety. Their stimulation causes an increase in heart rate and force of contraction thus increasing blood flow to the systemic and coronary circulation. Walking in a simple environment of open space is often challenging for patients, and walking in the complex environment of a busy street or shopping centre may be impossible without the component of automaticity. Levels also relate to the rate of synthesis in the liver and may rise in infections and pregnancy. The thalamus is a collection of nuclei that relay information between the cerebral cortex and the periphery, spinal cord, or brain stem. Leiomyoma is a tumour of the muscular wall of the uterus, usually benign, but can become malignant (leiomyosarcoma). Nevertheless, there has been significant improvement in survival recently due to better treatment of organ-based complications, and the overall 5-year survival now approaches 80%. The costomediastinal recesses are slit-like spaces situated between the costal and mediastinal pleurae. Fractures and dislocations are the most common traumatic injuries sustained by the bones. The suprascapular notch is located lateral to the midpoint of the superior border. Decreased sensation due to primary sensory impairments or secondary to reduced motor activity, such as in learned nonuse, results in reduced feedback (Taub 1980). The instrument used is called a sphygmomanometer, and two variables are measured: 1. We will also focus on the relationships of these organs with one another and some important clinical points related to these organs. Ligament between the neck of a rib and the transverse process of the corresponding vertebra. The iliolumbar artery and lateral sacral arteries also arise from the posterior division. In young women the condition is often a harmless nuisance, requiring warm gloves and sometimes vasodilators. The salts contained in bile act like a detergent to emulsify fat, that is, to break up fat into small droplets that can be acted on more effectively by digestive enzymes.

However, there are no convincing pathognomonic, non-invasive radiographic, historical, or physical examination findings that allow the reliable identification of lumbar facet joints as a source of low-back pain and referred lower extremity pain [69, 70]. You can feel the larynx move upward toward the epiglottis during this process by placing the flat ends of your fingers on your larynx as you swallow. Relationship between Anatomy & Physiology Form is closely related to function in all living things. Background Information Nervous System Review In Lesson 4 nervous tissue and the nervous system was introduced. Note also on this view the round ligament of the uterus passing on each side anteriorly toward (through) the inguinal canal (see later in lecture). The lymph from the superficial tissue of the perineum drains to the superficial inguinal nodes. The sternoclavicular joint is indirectly supported by the costoclavicular ligament (costo- = "rib"), which spans the sternal end of the clavicle and the underlying first rib. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Chemical digestion consists of numerous chemical reactions catalyzed by enzymes in saliva, gastric juice, pancreatic juice, and intestinal juice. Proximal muscle weakness, elevated muscle enzymes, myopathic changes on electromyography and inflammatory changes on muscle biopsy are diagnostic criteria for polymyositis. Ligament running between the styloid process and the lesser horn of the hyoid bone. The many substances necessary for clotting are normally inactive in the blood stream. Using the integumentary system model and the virtual microscope slide, view and identify the epidermis, dermis, and hypodermis. Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist. A range of blood test abnormalities in rheumatological disease are shown in Table 24. Intrinsic (intrathyroidal) mechanisms, as well as bioavailability of iodine, influence thyroid hormone production. It consists of 8 to 18 renal pyramids, which are longitudinally striped, one cone shaped area. These rami supply the muscles and skin over the posterior aspect of the body but give no branches to the limbs. Roughened prominence on the medial aspect of the radius about 2 cm distal to the proximal end. Hypodermis is composed of loose, fibrous connective tissue, which is richly supplied with lymphatic and blood vessels and nerves. Collective term for the ethmoidal air cells situated between the orbital and nasal cavities. For example, if the cerebrum sends a command down to the spinal cord to initiate walking, a copy of that motor command is sent to the cerebellum. This is the attachment site of the interosseous membrane of the leg, the sheet of dense connective tissue that connects the tibia and fibula bones. Apply Learning Outcome 2 to describe an example action associated with each muscle of the head, neck, and trunk. These partnerships ebb and flow between different members of the team, depending on where within the journey of recovery the patient lies. Restraint of the less affected body parts manually during a therapy session may be used to assist activation of the affected parts (Raine 2007). Achondroplasia is a congenital anomaly resulting in dwarfism due to abnormally short long bones. The signal transduction of the -adrenergic receptor pathway is discussed further in Chapter 1. Blood tests and plain radiographs are not necessary in the absence of "red flags" unless there is a failure to respond to treatment. The portion of this membrane that lines the abdomen is called the parietal peritoneum; that covering the organ is called the visceral peritoneum.

Determine the mode of onset and duration of the pain, nature, site, radiation, temporal characteristics, exacerbating and relieving the neck and shoulder are two of the most common sources of musculoskeletal pain. It is thought that a central nervous system model of body dynamics is essential to anticipatory control of posture during movement (Frank & Earl 1990). Clinical relevance Initiation of the first step from a quiet stance involves moving the centre of mass outside the base of support, transferring weight over the support limb and moving the swing limb forward (Patla 1996). Note also the genital branch passing through the spermatic cord to supply the cremasteric muscle (involved in the cremasteric reflex) - the lateral cutaneous nerve of the thigh, supplying cutaneous innervation to the lateral border of the thigh. The urogenital system refers to the organ system consisting of the reproductive and the urinary organs. Classification of exocrine glands They are classified by their structure and shape of the secretary portion. It helps to remember that supination is the motion you use when scooping up soup with a spoon. It varies greatly in shape and extent and is largely obliterated by sexual intercourse or childbirth; (g) Perineum, which is the tissue situated between the vaginal orifice and the anus. In addition, because the tendon of insertion passes posterior to the lateral malleolus, the plantar surface of the foot is pulled posteriorly, resulting in plantarflexion. The therapist is now in a position to select the most appropriate outcome measure to reflect change in the selected target. The esophagus has a physiological sphincter at its lower end, but such is not demonstrable anatomically. The slower current does not normally constitute a major factor in phase 0 depolarization of the atrial and ventricular myocardium and Purkinje fibers, but it persists after rapid depolarization and is responsible for the prolonged plateau phase characteristic of these fibers. Describing sensory function using the terms sensation and perception implies specific meaning and the two terms cannot be used interchangeably. Both the tricuspid and mitral valves are attached by means of thin fibrous threads to the wall of the ventricles. In humans, this is restricted to the visible spectrum of light and the cone opsins are commonly referred to by the primary colors most associated with the spectrum: red, green, and blue. Kanayama M, Hashimoto T, Shigenobu K, Togawa D, Oha F (2007) A minimum 10-year follow-up of posterior dynamic stabilization using Graf artificial ligament. White matter made up of bundles of neuronal fibers (tracts), composes most of the interior of the cerebrum. It is 15 relatively mobile because it is not fused with the lateral collateral ligament. Surgical removal of calcific deposits may be of benefit if conservative treatments fail. The occipital bone is the single bone that forms the posterior skull and posterior base of the cranial cavity. Central canal Source Material University of Michigan Virtual Microscope: histology. It is used in combination with methotrexate to minimize the risk of immune reactions. Sensory, or afferent, neurons carry information about the environment towards the central nervous system. This produces compression of the nerve, resulting in carpal tunnel syndrome, which is characterized by pain or numbness, and muscle weakness in those areas of the hand supplied by this nerve. Nevertheless problems have been identified with using this measure, with neurological patients in particular, the difficulty of facilitating patients with cognitive and perceptual problems to identify specific goals and use the scoring system (Bodiam 1999; Phipps & Richardson 2007). Table 7-2 shows some of the actions of these two systems 180 Human Anatomy and Physiology Table 7-2 Effects of the sympathetic and Parasympathetic Systems on Selected Organs Effector Pupils of eye Sweat glands Digestive glands Heart Bronchi of lungs Muscles of digestive system Kidneys Urinary bladder and emptying Liver Penis Adrenal medulla Blood Skin Respiratory system Digestive organs vessels to skeletal muscles Constriction Dilation Constriction None Constriction Dilation Increased release of glucose Ejaculation Stimulation Dilation Erection None Constriction None Sympathetic system Dilation Stimulation Inhibition Increased rate and strength of beat Dilation Decreased contraction (peristalsis) Decreased activity Relaxation None Contraction Parasympathetic System Constriction None Stimulation Decreased rate and strength of beat Constriction Increased contraction 181 Human Anatomy and Physiology Sense Organs Classification of sense organs the sense organs are often classified as special sense organs and general sense organs. At the outer and upper part the glenoid cavity receives the rounded head of the humerus. Identify each of the epithelial and connective tissue types and sub-types via a picture or diagram 6. Additionally, the levator labii superioris inserts into the skin of the upper lip to raise and protrude the upper lip, showing the upper gums.

An example of interval data might be a self-report quality-of-life scale where a score of 0 cannot indicate no quality of life. Filtration, small molecules pass through selectively permeable membrane in response to force of pressure. The human liver is the same reddish brown color as the animal liver seen in the supeln1arket. Distal initiation of limb movement will facilitate anticipatory activation of abdominal and hip musculature (core stability). Pulmonary hypertension is associated with a poor prognosis, especially in pregnancy. Roughened area located on the plantar aspect of the distal end of the distal phalanx for attachment of the tactile pads. Other elbow disorders Arthritis of the elbow joint may be due to systemic inflammatory arthritides, including rheumatoid and seronegative arthritis, crystal-induced synovitis (gout or pseudogout) and, rarely, septic arthritis. For example, at the atlantoaxial joint, the first cervical (C1) vertebra (atlas) rotates around the dens, the upward projection from the second cervical (C2) vertebra (axis). The germinal tissue contains two types of cells: spermatogenetic cell producing or developing the sperm cell and the sustentacular cell, which provide nourishment for the germinal sperm. Origin and Insertion Origin: distal anterior fibula Insertion: anterior aspect of the base of the fifth metatarsal Anterior, distal fibula Peroneus tertius Origin Insertion Actions Everts the foot and dorsiflexes the ankle Explanation of Actions Because peroneus tertius crosses the lateral aspect of the ankle and its origin is proximal to insertion, this muscle causes foot eversion. Treatment is usually by splinting the distal interphalangeal joint in extension or, rarely, surgery. This disparity in growth continues to increase; in the adult the cord ends in the region just below the area to which the last rib attaches (between the first and the second lumbar vertebrae. Human physiology is the scientific study of the chemistry and physics of the structures of the body and the ways in which they work together to support the functions necessary for life. Uterine sensitivity to oxytocin is greatly enhanced by estrogen and inhibited by progesterone. The advantage is that the screws can be used as a minimally invasive posterior stabilization technique and can often be combined with an anterior interbody fusion [191], which can also be done minimally invasively (see below, Case Introduction) [21]. Bacteria are microorganisms, tiny living bodies visible only through a microscope. They can present with mucocutaneous manifestations, fever, malaise, polyarthralgia, lymphadenopathy and serological abnormalities, such as positive tests for antinuclear antibodies and rheumatoid factor. Digital ischaemia usually presents as sudden onset of a small, cool, cyanotic and painful area of the foot (usually the toe). These facts greatly limit treatment recommendations on degenerative lumbar spondylosis. The superior and inferior articular processes of the cervical vertebrae are flattened and largely face upward or downward, respectively. The mouth, nose, sinuses, throat and chest act as resonators; they affect the quality and volume of speech while the lips, tongue and teeth convert the sounds into speech. Endochondrial ossification produces long bones and all other bones not formed by intra-membranous ossification. Also, the relative space allotted for the different regions is exaggerated in muscles that have greater innervation. Antiresorptive agents Bisphosphonates-Alendronate and risedronate are available as once-weekly preparations with evidence for significant reductions in vertebral and non-vertebral fractures. As a junior doctor, I assumed that this wretched state of affairs was an inevitable consequence of stroke. The first metacarpal bone of the thumb is the shortest and most mobile of the metacarpals and lies in a different plane to the others. Efficient interaction of these components allows us to adapt our performance to different demands. The red marrow also known as myeloid tissue Endosteum is the lining the medullary cavity of compact bone tissue and covering the trabeculae of spongy bone tissue. This provides more "trigger" calcium and more calcium for contraction, resulting in a positive inotropic effect.

The presence of melanin a dark pigment produced by specialized cell called melanocyte 2. Strong fibrous band within and above the articular capsule serving to protect and hold together the clavicle and acromion. The physiological significance of this is not entirely clear, but it has been suggested that it helps to stabilize joints during isotonic contractions. After the ventricles have emptied, both chambers are relaxed for a short period of time as they fill with blood. Supination and pronation are the movements of the forearm that go between these two positions. It is thick semi transparent, elastic fluid containing suspended particles and a series of minute tubules and filaments that form cytoskeleton. The meninges that form the protective covering around the spinal cord also extend up and around the brain to enclose it completely. Anterior opening in the medial wall of the orbit between the frontal and ethmoid bones for passage of the anterior ethmoidal nerve and vessels from the anterior cranial fossa. Foramen between the greater sciatic notch, sacrum, sacrospinous ligament and the upper part of the sacrotuberous ligament. Secondly, control of the position of the centre of mass for static or dynamic equilibrium is involved in both gait and posture (Grasso et al. If the cause of a movement compensation is the lack of posture and balance, then it is only giving the patient more appropriate control over their posture and balance that will ultimately reduce the presentation of the compensation. Abdominal muscles are contracted to increase intra-abdominal pressure during forced expiration, micturition, defecation, and parturition. Stratified columnar epithelium is found in milk duct of mammary gland & anus layers. Within the medulla are organized areas called renal pyramids, with a base at the cortex and an apex (papilla) pointing into the renal pelvis. With treatment, the normocytic normochromic anaemia corrects, and the slight increase in hepatic alkaline phosphatase sometimes noted in active disease is reduced. Adductor hallucis is similar to adductor pollicis in that both muscles have a transverse head and an oblique head. The complex drainage of the ovaries, uterus and vagina is summarized on this slide. This fluid also provides nourishment to the articular cartilage, which does not contain blood vessels. The tectospinal tract projects from the midbrain to the spinal cord and is important for postural movements that are driven by the superior colliculus. Motor learning can be divided into three distinct phases (Halsband & Lange 2006): 1. The complex interplay of ionic currents that constitute the cardiac action potential is based on the ability of ion channels to sense and respond to variations in the membrane potential. A pattern of ridges and grooves on the deep surface of the epidermis fit a complementary pattern of corrugations of the underlying dermis. Proteins are the principal constituents of cytoplasm and are essential to the growth and the rebuilding of body tissues. For females, this stage is characterized by the start of menstruation or menses (men/o = month). The spermatic cord contains arteries, veins, ducts, nerves, and lymphatic vessels. Lidocaine also reduces delayed afterdepolarizations seen with digoxin Lidocaine Lidocaine has been used as a local anesthetic for more than half a century. Acupuncture might provide short-term pain relief in people with chronic neck pain, but evidence is limited. A B 27 11 14 15 16 13 12 28 29 17 18 19 20 21 22 23 24 19 16 14 Iliopubic (iliopectineal) eminence. The anterior portion of gluteus medius and gluteus minimus perform medial rotation of the hip because the anterior aspect of the origin attachments of these muscles is more anterior than the greater trochanter.

In the dorsal cavity, the cranial cavity houses the brain, and the vertebral (spinal) cavity encloses the spinal cord. The dendrites are usually highly branched processes, providing locations for other neurons to communicate with the cell body. The provision of a systematic programme of sensory stimulation and heightened awareness of the hemiparetic hand is very important if there are positive indications for functional recovery. There is generally a higher prevalence of gout in indigenous ethnic groups around the Pacific Rim. Annular fibrous connection between adjacent vertebral bodies consisting of obliquely oriented connective tissue fibers arranged in alternating directions. The lupus anticoagulant test measures the ability of antiphospholipid antibodies to prolong clotting times. First is the mucous membrane, so called because its epithelial layer contains many mucus-secreting cells. Lymphatic ducts are ducts that drains different parts of the body and includes: 289 Human Anatomy and Physiology a. Taking the patient to a dual tasking level is an essential role of rehabilitation, because it represents life in the real world. Avascular necrosis Segmental avascular necrosis of the weight-bearing portion of the femoral head can occur. Fibrous brace on the plantar aspect of the foot between the lateral cuneiform and cuboid bones. The anal triangle contains the external anal sphincter, seen in both the male and female perineum. The lymphatic drainage of the prostate is through the internal and external nodes, draining then into the common iliac nodes. Loss of length and strength in soleus as an antagonist will also significantly contribute to poor dorsiflexion of the foot. The duodenum is the portion of the small intestine that is the first to receive the contents of the stomach. Exercises-Gentle neck exercises may be a useful and effective treatment for acute neck pain. Suggested mechanisms include increased intra-capsular and intra-osseous pressure, subchondral microfracture and enthesopathy or bursitis secondary to muscle weakness and structural alteration. Although the nervous system was thought to be irreparable, Mrs Bobath found changes in clinical presentation that demonstrated modification of the nervous system. Drugs administered orally are largely used to prevent the recurrence of arrhythmias, whereas drugs administered parenterally are usually given to treat acute disorders. Together, the radiocarpal and midcarpal joints are responsible for all movements of the hand at the wrist. The gall bladder lies just anterior to the 1st part and the upper portion of the 2nd part of the duodenum. Improved left hip extension/abduction at the left hip with improved pelvic alignment. If efficiency in the motor skill is inadequate, the therapist may look at movement components to improve skill. The ligaments described in the previous slides maintains the orientation and provide some support of the uterus and associated structures with the levator ani muscles providing strong support to the uterus. The bones of the shoulder region form the pectoral girdle, which anchors the upper limb to the thoracic cage of the axial skeleton. They distribute to the mediastinal pleura and then to the muscle of the dome of the diaphragm (see the thoracic contents lecture). The outcome may be assessed either formatively or quantitatively, and depending upon the result of the intervention there may be a 45 Bobath Concept: Theory and Clinical Practice in Neurological Rehabilitation requirement to re-evaluate the hypothesis or consider the effectiveness of the treatment intervention. Bacterial infections involve the commonly occurring pyogenic organisms such as Staphylococcus species and Escherichia coli. Tunica albuginea is a thick connective tissue layer found on the surface of the testis just deep to the tunica vaginalis.
