| inferior cerebellar peduncle | Large paired bundles of nerve fibres which develop on the dorsolateral surfaces of the upper medulla, extend under the lateral recesses of the rhomboid fossa and curve dorsally into the cerebellum medial to the middle cerebellar peduncle; composed of a larger (lateral) bundle, the restiform body, and a small (medial) bundle, the juxtarestiform body. Fibres forming this composite bundle originate from spinal neurons and medullary relay nuclei. The largest constituent (restiform body) is crossed fibres from the inferior olive; it also contains the dorsal spinocerebellar tract and cerebellar projections from the lateral reticular nucleus, the accessory cuneate nucleus, the paramedian reticular nuclei and the perihypoglossal nuclei. Vestibulocerebellar fibres are placed medially in the inferior cerebellar peduncle and are usually separately identified as the juxtarestiform body. Synonym: pedunculus cerebellaris inferior.

| inferior surface of cerebellar hemisphere | It rests in the posterior cranial fossa and overlies the medulla; it includes the semilunaris inferior, biventer lobule, cerebellar tonsil, and flocculus. Synonym: facies inferior hemispherii cerebelli. (05 Mar 2000) |
| inferior veins of cerebellar hemisphere | Several veins draining the inferior portion of the cerebellar hemispheres; they terminate in the petrosal vein. Synonym: venae hemispherii cerebelli inferiores. (05 Mar 2000) |
| juvenile cerebellar astrocytoma | <oncology, tumour> This primary brain tumour of the cerebellum accounts for 10 to 30% of brain tumours in children. The are usually slow growing and benign. Symptoms include gait problems, clumsiness, headache and vomiting. Treatment often involves a combination of surgery, radiation therapy and chemotherapy. (27 Sep 1997) |
| layers of cerebellar cortex | The thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of Purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum. Synonym: cortex cerebelli. (05 Mar 2000) |
| acute reflex bone atrophy | Atrophy of bones, commonly of the carpal or tarsal bones, following a slight injury such as a sprain. See: causalgia, reflex sympathetic dystrophy. Synonym: acute reflex bone atrophy, posttraumatic osteoporosis, Sudeck's syndrome. Origin: L. English sweat (05 Mar 2000) |
| acute yellow atrophy of the liver | A lesion in which there is extensive and rapid death of parenchymal cells of the liver, sometimes with fatty degeneration of the size of the organ; the necrosis may result from fulminant viral infection or chemical poisoning; associated with jaundice. Synonym: acute parenchymatous hepatitis, Rokitansky's disease. (05 Mar 2000) |
| alveolar atrophy | Diminution in size of the supportive tissues of the teeth due to lack of function, reduced blood supply, or unknown causes. (05 Mar 2000) |
| arthritic atrophy | Atrophy of muscles rendered inactive by a chronically inflamed or fixed joint. (05 Mar 2000) |
| atrophy | <pathology> A wasting away, a diminution in the size of a cell, tissue, organ or part. Origin: L., Gr. Atrophia (16 Dec 1997) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| blue atrophy | Depressed blue atrophic scars due to injections in the skin of impure substances, as seen in narcotics addicts. (05 Mar 2000) |
| brown atrophy | Atrophy of the heart wall, especially in the elderly, in which the muscle is dark reddish brown and reduced in volume; the muscle fibres become pigmented especially about the nuclei, by lipochrome granules. (05 Mar 2000) |
| Buchwald's atrophy | A progressive form of cutaneous atrophy. (05 Mar 2000) |
| macular atrophy | Atrophoderma in which the skin becomes bag like and wrinkled. Synonym: atrophia maculosa varioliformis cutis, atrophoderma maculatum, macular atrophy, primary idiopathic macular atrophy, primary macular atrophy of skin. Origin: G. Anetos, relaxed, + derma, skin (05 Mar 2000) |
