| cerebellar fissures | The deep furrows which divide the lobules of the cerebellum. See: postcentral fissure, primary fissure of cerebellum, secondary fissure of cerebellum. Synonym: fissurae cerebelli. (05 Mar 2000) |
|---|---|
| cerebellar fossa | The large concave impressions on the inner surface of the occipital bone on either side of the foramen magnum and internal occipital crest, housing the cerebellar hemispheres; a part of the posterior cranial fossa. (05 Mar 2000) |
| cerebellar frenulum | A band passing from the longitudinal groove between the quadrigeminal bodies on to the superior medullary velum. Synonym: frenulum veli medullaris superioris, cerebellar frenulum, frenulum cerebelli. (05 Mar 2000) |
| cerebellar gait | Wide-based gait with lateral veering, unsteadiness, and irregularity of steps; often with a tendency to fall to one or other side, forward or backward. Synonym: ataxic gait. (05 Mar 2000) |
| cerebellar hemisphere | The large part of the cerebellum lateral to the vermis cerebelli. Synonym: hemispherium cerebelli, hemispherium. (05 Mar 2000) |
| cerebellar herniation | A condition that occurs when the brain is under abnormally increased pressure. The increased intracranial pressure forces the brain downward inside the skull. This results in typical neurologic manifestations (coma, paralysis and a unilateral dilated pupil). May occur secondary to head injury, primary or metastatic brain tumour, bacterial meningitis and brain abscess. Brain herniations may involve different portions of the brain such as the cerebellum (cerebellar herniation), uncus (uncal herniation) and transtentorial herniation of the cerebrum. (27 Sep 1997) |
| cerebellar neoplasms | Neoplasms located in the cerebellum. (12 Dec 1998) |
| 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) |
