| progressive cerebellar tremor | <syndrome> An intention tremor beginning in one extremity, gradually increasing in intensity, and subsequently involving other parts of the body. Synonym: progressive cerebellar tremor. Facial paralysis, otalgia, and herpes zoster resulting from viral infection of the seventh cranial nerve and geniculate ganglion, a form of juvenile paralysis agitans associated with primary atrophy of the pallidal system. Synonym: paleostriatal syndrome, pallidal syndrome. Synonym: Ramsay Hunt's syndrome. (05 Mar 2000) |

| hereditary cerebellar ataxia | A disease of later childhood and early adult life, marked by ataxic gait, hesitating and explosive speech, nystagmus, and sometimes optic neuritis. It probably comprises several distinct conditions with diverse patterns of inheritance. Collective term for a number of hereditary disorders in which cerebellar signs are the most prominent finding. (05 Mar 2000) |
| nutritional type cerebellar atrophy | A restricted type of cerebellar cortical degeneration, affecting particularly the Purkinje cells of the anterior and superior vermis; probably caused by thiamin deficiency; most frequently seen in chronic alcoholics and then called alcoholic cerebellar degeneration. (05 Mar 2000) |
| superior cerebellar artery | <anatomy, artery> Origin, basilar; distribution, upper surface of cerebellum, colliculi, and most of the cerebellar nuclei; anastomoses, posterior inferior cerebellar. Synonym: arteria cerebelli superior. (05 Mar 2000) |
| superior cerebellar artery syndrome | <syndrome> Syndrome due to thrombosis of the superior cerebellar artery which supplies the spinothalamic tract and the superior cerebellar peduncle; there is incoordination in performing skilled movements, with loss of pain and temperature senses on the side of the face and body opposite to that of the lesion. (05 Mar 2000) |
| superior cerebellar peduncle | A large bundle of nerve fibres that originate from the dentate and interpositus nuclei and emerges from the cerebellum in the rostral direction, along the lateral wall of the fourth ventricle. The bundle submerges from the dorsal surface of the brainstem into the mesencephalic tegmentum, where all of its fibres cross in the massive decussation of the superior cerebellar peduncles. Part of the bundle terminates in the contralateral red nucleus; the bulk of the fibres continue rostrally to parts of the ventral intermediate nucleus of thalamus, ventral posterolateral nucleus of thalamus, and central lateral nucleus of thalamus. Synonym: pedunculus cerebellaris superior, brachium conjunctivum cerebelli. (05 Mar 2000) |
| superior surface of cerebellar hemisphere | It lies against the under surface of the tentorium and includes the ala lobuli centralis, quadrangular lobule, simple lobule, and superior semilunar lobule. Synonym: facies superior hemispherii cerebelli. (05 Mar 2000) |
| superior veins of cerebellar hemisphere | Several veins draining the superior part of the cerebellar hemispheres; they terminate in the superior petrosal sinus or the petrosal vein. Synonym: venae hemispherii cerebelli superiores. (05 Mar 2000) |
| decussation of superior cerebellar peduncles | The decussation of the left and right superior cerebellar peduncles in the tegmentum of the caudal mesencephalon. Synonym: decussatio pedunculorum cerebellarium superiorum, decussatio brachii conjunctivi, decussation of brachia conjunctiva, Wernekinck's decussation. (05 Mar 2000) |
| dentatorubral cerebellar atrophy with polymyoclonus | A familial disorder beginning in late childhood, characterised by progressive cerebellar ataxia, action myoclonus and preserved intellect. Probably due to multiple causes, mitochondrial abnormalities being one. Synonym: dentatorubral cerebellar atrophy with polymyoclonus. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| 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) |
