What does the inferior cerebellar peduncle do?
Function. The inferior cerebellar peduncle carries many types of input and output fibers that are mainly concerned with integrating proprioceptive sensory input with motor vestibular functions such as balance and posture maintenance.
What is the difference between the cerebral peduncles and the cerebellar peduncles?
Cerebellar peduncles connect the cerebellum to the brain stem. There are six cerebellar peduncles in total, three on each side: Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain….Cerebellar peduncle.

What supplies the inferior cerebellar peduncle?
The inferior cerebellar peduncles predominantly receive their arterial blood supply from branches of the posterior inferior cerebellar artery 1-3.
Which part of the brainstem contains the cerebellar peduncles?
midbrain
The cerebral peduncles are located on either side of the midbrain and are the frontmost part of the midbrain, and act as the connectors between the rest of the midbrain and the thalamic nuclei and thus the cerebrum.
Where is cerebellar nuclei?
cerebellum
The cerebellar nuclei comprise 4 paired deep grey matter nuclei deep within the cerebellum near the fourth ventricle. They are arranged in the following order, from lateral to medial: dentate nuclei (the largest and most lateral)
What is the other name of peduncle?
The main stem of a herbaceous plant. stalk. shoot. stem. trunk.
How are the vestibular nuclei connected to the cerebellum?
A few of the vestibular afferents go directly to the cerebellum through the inferior cerebellar peduncle. The cerebellum coordinates the movements that maintain balance. There are many connections between the cerebellum and the vestibular nuclei. Summary of ascending and descending vestibular pathways.
Where is the cerebellar peduncle located in the brain?
Cerebellar Peduncles. The basilar pons, which is located inferior to the exiting roots of the trigeminal nerve, is continuous into the middle cerebellar peduncle ( brachium pontis ), which is located superior (dorsal) to the exiting roots of the fifth cranial nerve ( Figs. 27.1A-C and 27.2 ).
What is the difference between the inferior and middle cerebellar peduncle?
The inferior cerebellar peduncle contains four afferent tracts (posterior spinocerebellar, vestibulocerebellar, olivocerebellar and reticulocerebellar) and one efferent tract (the cerebellovestibular tract). The middle cerebellar peduncle is the largest and contains only afferent fibres from the pontine nucleus.
What are the nuclei of the cerebellum?
solitary tract nucleus ambiguus nucleus dorsal vagal motor nucleus hypoglossal nucleus cerebellum (part of metencephalon) vermis cerebellar hemisphere cerebellar tonsil dentate nucleus cerebellar peduncles superior cerebellar peduncle middle cerebellar peduncle inferior cerebellar peduncle cranial meninges (meninx primitiva)
