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.

Inferior cerebellar peduncle is a thick rope-like strand that occupies the upper part of the posterior district of the medulla oblongata. The peduncles form the lateral border of the fourth ventricle , and form a distinctive diamond – the middle peduncle forming the central corners of the diamond, while the superior and inferior peduncles ...
The juxtarestiform body is the smaller, medial subdivision of each inferior cerebellar peduncle (the other, lateral one being the restiform body). [1]: 290 The juxtarestiform body contains mostly cerebellar afferents, but also some cerebellar efferents. [1]: 290
The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
They in turn project efferents into the cerebellum through the inferior cerebellar peduncle as: [1] the anterior internal arcuate fibers which pass along the midline before decussating near the rhomboid fossa (floor of fourth ventricle) then passing laterally as the medullary striae; the anterior external arcuate fibers.
Directly rostral to the superior cerebellar peduncle, there is the superior medullary velum and then the two trochlear nerves. This marks the end of the pons as the inferior colliculus is directly rostral and marks the caudal midbrain. Middle cerebellar peduncle is located inferior and lateral to the superior cerebellar peduncle, connecting ...
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.
