| cerebellar nuclei | Four accumulations of gray substance embedded in the white substance of the cerebellum, comprising the nucleus dentatus, nucleus emboliformis, nucleus globosus, and nucleus fastigii. (12 Dec 1998) |
|---|---|
| cerebellar pyramid | A subdivision of the inferior vermis of the cerebellum between the tuber and the uvula. Synonym: pyramis vermis, cerebellar pyramid. Pyramid of vestibule, the upper triangular extremity of the crista vestibuli. Synonym: pyramis vestibuli. (05 Mar 2000) |
| cerebellar rigidity | Increased tone of the extensor muscles, related to injury of the vermis of the cerebellum. (05 Mar 2000) |
| cerebellar speech | An explosive type of utterance, with slurring of words. (05 Mar 2000) |
| cerebellar sulci | Grooves between the folia cerebelli; commonly called fissures in cerebellum. (05 Mar 2000) |
| cerebellar syndrome | <syndrome> The signs and symptoms of cerebellar deficiency: dysmetria, dysarthria, asynergia, nystagmus, ataxia, staggering gait, and adiadochokinesia. (05 Mar 2000) |
| cerebellar tonsil | A rounded lobule on the undersurface of each cerebellar hemisphere, continuous medially with the uvula of the cerebellar vermis. Synonym: tonsilla cerebelli, amygdala cerebelli. (05 Mar 2000) |
| cerebellar veins | The veins draining the cerebellum. See: inferior veins of cerebellar hemisphere, superior veins of cerebellar hemisphere, petrosal vein, precentral cerebellar vein, inferior vein of vermis, superior vein of vermis. Synonym: venae cerebelli, veins of cerebellum. (05 Mar 2000) |
| granular layer of cerebellar cortex | The deepest of the three layers of the cortex; it contains large numbers of granule cells, the dendrites of which synapse with incoming mossy fibres in cerebellar glomeruli. Thin, unmyelinated axons of granule cells ascend perpendicularly into the molecular layer in which they bifurcate into fibres coursing parallel to the long axis of the cerebellar folia. Parallel fibres form numerous synapses with the dendrites of Purkinje cells, basket cells, and stellate cells. Synonym: stratum granulosum cerebelli, granular layer of cerebellar cortex. (05 Mar 2000) |
| middle cerebellar peduncle | The largest of three paired cerebellar peduncles, composed mainly of fibres that originate in the pontine nuclei, cross the midline in the ventral part of pons, and emerge on the opposite side as a massive bundle arching dorsally along the lateral side of the pontine tegmentum into the cerebellum; its fibres are distributed chiefly to the cortex of the cerebellar hemisphere. Synonym: pedunculus cerebellaris medius, brachium pontis. (05 Mar 2000) |
| molecular layer of cerebellar cortex | The outer lamina of the cortex, containing the cell bodies and dendrites of Purkinje cells, the axons of the granule cells, and the cell bodies, dendrites, and axons of basket cells. Synonym: stratum moleculare cerebelli, molecular layer of cerebellar cortex. (05 Mar 2000) |
| congenital cerebellar atrophy | Familial disorder that causes degeneration of various cells in the cerebellum. Two types are recognised, one in which the granular layer cells degenerate, the other in which the Purkinje cells degenerate. (05 Mar 2000) |
| posterior cerebellar notch | A narrow notch between the cerebellar hemispheres posteriorly, occupied by the falx cerebelli. Synonym: incisura cerebelli posterior, marsupial notch, posterior notch of cerebellum. (05 Mar 2000) |
| posterior inferior cerebellar artery | <anatomy, artery> Origin, vertebral; distribution, lateral medulla, choroid plexus of fourth ventricle, and cerebellum; anastomoses, superior cerebellar and anterior inferior cerebellar. Synonym: arteria cerebelli inferior posterior. (05 Mar 2000) |
| posterior inferior cerebellar artery syndrome | <syndrome> A syndrome due usually to thrombosis, characterised by dysarthria, dysphagia, staggering gait, and vertigo, and marked by hypotonia, incoordination of voluntary movement, nystagmus, Horner's syndrome on the ipsilateral side, and loss of pain and temperature senses on the side of the body opposite to the lesion. Synonym: lateral medullary syndrome, Wallenberg's syndrome. (05 Mar 2000) |
