  • posterior
  • The targeted region should be aimed inferior to the most prominent aspect of the greater trochanter, and medial to the landmark of the ischial tuberosity, at the depth of the posterior border of the proximal femur. (wikipedia.org)
  • nerves
  • These cysts, though rare, can be found to grow large - over 3-4 centimetres (1.2-1.6 in) in size, often causing severe abdominal pain from compression on the cyst itself as well as adjoining nerves. (wikipedia.org)
  • sciatic nerve
  • After skin and transducer preparation (see transducer preparation section), place a curved low frequency 2-5 MHz transducer firmly on the buttock region to capture the best possible transverse view of the sciatic nerve. (usra.ca)
  • Locating the sciatic nerve in this region can be challenging because of the required depth of penetration especially when there is an abundant amount of overlying adipose tissue. (usra.ca)
  • The largest nerve of the human body, the sciatic nerve is the main branch, that give rami to the motor innervation of the muscles of the foot, the leg and the thigh. (wikipedia.org)
  • The sciatic nerve (L4 to S3), the largest nerve of the body, immediately leaves the pelvis through the greater sciatic foramen, below the piriformis. (wikipedia.org)
  • cord
  • Normal Development of the Lateral Motor Column in the Brachial Cord in Rana pipiens' EMANUEL D. POLLACK Department of Zoology, University of lowa, Iowa City, Iowa ABSTRACT Counts of differentiating motor cells over the length of the brachial lateral motor column (LMC) indicate that a large decrease in cell number takes place during the larval period. (docme.ru)
  • In X . Zaevis, the LMC of the lumbosacral cord appears prior to that of the brachial region (Kollros, '56), and for a large portion of the larval period maintains a lead over the brachial region in its level of differentiation. (docme.ru)
  • Also, the spinal cord has a varying width, ranging from 13 mm (1⁄2 in) thick in the cervical and lumbar regions to 6.4 mm (1⁄4 in) thick in the thoracic area. (wikipedia.org)
  • In cross-section, the peripheral region of the cord contains neuronal white matter tracts containing sensory and motor axons. (wikipedia.org)
  • occur
  • In Amblystma, locomotor response and reflex activities occur first in the more cephalic regions of the body (Coghill, '29). (docme.ru)
  • nerve
  • Its smaller motor branches are distributed directly to psoas major, while the larger branches leave the muscle at various sites to run obliquely down through the pelvis to leave under the inguinal ligament, with the exception of the obturator nerve which exits the pelvis through the obturator foramen. (wikipedia.org)
  • Internal to this peripheral region is the grey matter, which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly-shape. (wikipedia.org)
  • diagnosis
  • Given the key role of electrodiagnostic testing in the diagnosis of acute and chronic radiculopathies, the American Association of Neuromuscular & Electrodiagnostic Medicine has issued evidence-based practice guidelines, for the diagnosis of both cervical and lumbosacral radiculopathies. (wikipedia.org)
  • neurons
  • As excitatory signaling increases, larger motor neurons are subsequently recruited and contraction strength increases. (wikipedia.org)
  • Another key benefit derived from the size principle is that smaller neurons will be fired more regularly and for a longer duration of time compared to larger neurons. (wikipedia.org)
  • often
  • They are often the result of a population bottlenecks from larger populations, leading to reduced genetic diversity and loss or fixation of alleles and shifts in allele frequencies. (wikipedia.org)
  • Superior vena cava syndrome The superior vena cava (a large vein carrying circulating, de-oxygenated blood into the heart) may be compressed by a tumor, most often non-small-cell lung carcinoma (50 percent), small-cell lung carcinoma (25 percent), lymphoma, or metastasis, causing superior vena cava syndrome. (wikipedia.org)
  • inguinal
  • Its terminal branch then runs parallel to the inguinal ligament to exit the aponeurosis of the abdominal external oblique above the external inguinal ring where it supplies the skin above the inguinal ligament (i.e. the hypogastric region) with the anterior cutaneous branch. (wikipedia.org)
  • In the region of the groin, the inguinal canal, a passage through the layers. (wikipedia.org)
  • lower
  • Usually, the large joints of the lower limb are aligned in a straight line, which represents the mechanical longitudinal axis of the leg, the Mikulicz line. (wikipedia.org)
  • pain
  • Sacroiliac joint dysfunction generally refers to pain in the sacroiliac joint region that is caused by abnormal motion in the sacroiliac joint, either too much motion or too little motion. (wikipedia.org)
  • Women who have delivered large babies or who have had extended labors also are prone to developing chronic sacroiliac joint pain and instability. (wikipedia.org)
  • changes
  • Within the central nervous system of amphibians there are several instances of the more cephalic regions undergoing developmental changes earlier than the more caudal regions. (docme.ru)
  • abdominal
  • Digestive tract: Stomach, small intestine, large intestine with cecum and appendix Accessory organs of the digestive tract: Liver, gallbladder and pancreas Urinary system: Kidneys and ureters - but technically located in retroperitoneum - outside peritoneal membrane Other organs: Spleen Abdominal organs can be highly specialized in some animals. (wikipedia.org)
  • Left
  • Description of Plate: Plate I: The Left and Right Kidney Regions: Plate A.(the Left) shows the Shadow of One Stone. (wikipedia.org)
  • likely
  • Again, smaller populations are more likely to become extinct due to these environmentally generated population fluctuations than the large populations. (wikipedia.org)
  • small
  • Small populations can behave differently from larger populations. (wikipedia.org)
  • The influence of stochastic variation in demographic (reproductive and mortality) rates is much higher for small populations than large ones. (wikipedia.org)
  • found
  • He found that an initial large LMC cell number per section during the early larval period was followed by a large decrease in cell number per section during the mid-larval stages and a much smaller subsequent decrease by the completion of metamorphosis. (docme.ru)
