| descending degeneration | Orthograde (wallerian) degeneration of an injured nerve fibre; i.e., distal to the lesion, degeneration caudal to the level of a spinal cord lesion. (05 Mar 2000) |

| descending genicular artery | <anatomy, artery> Origin, femoral, in adductor canal; distribution, penetrates vastoadductor fascia to supply knee joint and adjacent parts; anastomoses, medial superior genicular, medial inferior genicular, lateral superior genicular, lateral inferior genicular and anterior tibial recurrent arteries, i.e., articular network of knee. Synonym: arteria genus descendens, arteria anastomotica magna, descending artery of knee, great anastomotic artery. (05 Mar 2000) |
| descending neuritis | Inflammation progressing downward along a nerve trunk in a direction toward the periphery. (05 Mar 2000) |
| descending nucleus of the trigeminus | The long sensory nucleus extending from the caudal border of the pontine sensory nucleus of the trigeminus down through the lateral region of the rhombencephalon into the upper three segments of the spinal cord's dorsal horn; it receives the fibres of the sensory root of the trigeminal nerve which descend along its lateral border as the spinal tract of trigeminal nerve. Synonym: nucleus tractus spinalis nervi trigemini, descending nucleus of the trigeminus, spinal nucleus of the trigeminus. (05 Mar 2000) |
| descending palatine artery | <anatomy, artery> Origin, maxillary; distribution, soft palate, gums, and bones and mucous membrane of hard palate; anastomoses, sphenopalatine, ascending palatine, ascending pharyngeal, and tonsillar branches of facial. Synonym: arteria palatina descendens. (05 Mar 2000) |
| descending part of aorta | A part of the aorta, further divided into the thoracic aorta and the abdominal aorta. Synonym: pars descendens aortae, aorta descendens, descending part of aorta. (05 Mar 2000) |
| descending part of duodenum | descending part of duodenum |
| descending part of facial canal | Second portion of the facial canal, after the horizontal parts, beginning at the posterior end of the lateral crus where the canal begins to descend. It runs vertically downward, ending at the stylomastoid foramen. Anteriorly, the descending part of the facial canal communicates with the tympanic cavity via the canaliculus for the nerve to the stapedius muscle and the posterior canaliculus of the chorda tympani. (05 Mar 2000) |
| descending posterior branch | The descending posterior branch of the superior lobar branch of the right pulmonary artery. Synonym: ramus posterior descendens. (05 Mar 2000) |
| descending scapular artery | <anatomy, artery> Origin, subclavian or as the deep branch of the transverse cervical; distribution, passes deep to the rhomboid muscles, supplying them and other muscles and skin along the vertebral border of the scapula; anastomoses, suprascapular and scapular circumflex. Synonym: arteria dorsalis scapulae, rami profundi arteriae transversae cervicis, ramus profundus arteriae transversae colli, arteria scapularis dorsalis, arteria scapularis descendens, deep branch of the transverse cervical artery, descending scapular artery, ramus profundus arteria scapularis descendens. (05 Mar 2000) |
| descending tract of trigeminal nerve | <anatomy, nerve> A compact fibre bundle, comma-shaped on transverse section, composed of primary sensory fibres of the portio major of the trigeminal nerve, descending from the level of the entrance of the trigeminus in the upper pons down through the dorsolateral region of the rhombencephalic tegmentum along the lateral side of the descending or spinal nucleus of the trigeminus, emerging on the dorsolateral surface of the lower medulla oblongata as the tuberculum cinereum, and continuing as far as the second cervical segment of the spinal cord. Its fibres are distributed to the descending or spinal nucleus of the trigeminus. Synonym: tractus spinalis nervi trigemini, descending tract of trigeminal nerve, tractus descendens nervi trigemini. (05 Mar 2000) |
| asymmetric motor neuropathy | Neuropathy in which the loss of function is more marked in the extremities of one side of the body, old term for diabetic polyradiculopathy. (05 Mar 2000) |
| autonomic neuropathy | <neurology, pathology> A group of symptoms which is caused by damage to the nerves which supply the internal organs. May be associated with diabetes, alcohol abuse, trauma (nerve injury) and the use of anticholinergic medications. Symptoms include abdominal swelling, heat intolerance, nausea, vomiting, impotence, diarrhoea, constipation, dizziness with standing, difficulty urinating and urinary incontinence. Origin: Gr. Pathos = disease (27 Sep 1997) |
| axillary neuropathy | <neurology, pathology> A condition involving dysfunction of the axillary nerve which normally supplies the deltoid and teres minor muscles and sensation to the lateral aspect of the shoulder. This condition is a type of peripheral neuropathy that may manifest as the result of a variety of disease processes or injuries. Conditions associated with axillary nerve dysfunction include mononeuritis multiplex, fracture of the humerus, abduction injury to the shoulder, pressure to the armpit from a cast, splint or crutches. Symptoms include numbness over the outer portion of the shoulder, shoulder weakness and difficulty lifting arm or objects over your head. An EMG, nerve conduction study or muscle biopsy can be helpful in making the diagnosis. Recovery is generally spontaneous if the underlying cause can be corrected and shoulder mobility is preserved. Corticosteroid injections may be indicated in some instances. Origin: Gr. Pathos = disease (27 Sep 1997) |
| brachial plexus neuropathy | A neurological disorder, of unknown cause, characterised by the sudden onset of severe pain, usually about the shoulder and often beginning at night, soon followed by weakness and wasting of various forequarter muscles, particularly shoulder girdle muscles; both sporadic and familial in occurrence with the former much more common; often preceded by some antecedent event, such as an upper respiratory infection, hospitalization, vaccination, or non-specific trauma; usually attributed to a brachial plexus lesion, because the nerve fibres involed are most often derived from the upper trunk, but actually multiple proximal mononeuropathies. Synonym: acute brachial radiculitis, brachial plexitis, brachial plexus neuropathy, Parsonage-Turner syndrome, shoulder-girdle syndrome. (05 Mar 2000) |
