| 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) |
| 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) |
| precentral cerebellar vein | <anatomy, vein> An unpaired vein originating in the precentral cerebellar fissure passing anterior and superior to the culmen on its way to terminate in the great cerebral vein. Synonym: vena precentralis cerebelli. (05 Mar 2000) |
| primary progressive cerebellar degeneration | A familial ataxic condition related to cerebellar degeneration. (05 Mar 2000) |
| 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) |
