The cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1] Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.
The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
The inferior cerebellar peduncle is the smallest of the three cerebellar peduncles. The upper part of the posterior district of the medulla oblongata is occupied by the inferior cerebellar peduncle, a thick rope-like strand situated between the lower part of the fourth ventricle and the roots of the glossopharyngeal and vagus nerves.
Superior cerebellar peduncles are connected together by the superior medullary velum, which can be followed upward as far as the inferior colliculi, under which they disappear. Below, they form the upper lateral boundaries of the fourth ventricle , but as they ascend they converge on the dorsal aspect of the ventricle and thus assist in forming ...
Finally, pontocerebellar projections carry vestibulo-occular signals to the contralateral cerebellum via the middle cerebellar peduncle. [5] The rostral half of the flocculus also receives mossy fiber projections from the pontine nuclei; however, it receives very little projection from the vestibular system.
Joubert syndrome; Other names: CPD IV [1] (A) MRI Brain, axial T2 sequence showing enlarged superior cerebellar peduncles and vermian hypoplasia resulting in characteristic "molar tooth" appearance; (B) MRI Brain, sagittal T2 (a) and T1 (b) sequences showing vermian hypoplasia, predominantly at the superior aspect
crus means ‘leg’ in Latin.) is the anterior portion of the cerebral peduncle which contains the motor tracts, traveling from the cerebral cortex to the pons and spine. The plural of which is cerebral crura. In some older texts, this is called the cerebral peduncle, but presently, it is usually limited to just the anterior white matter ...
