Middle cerebellar peduncle

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 The trigeminal nerve (CN V) arises from the lateral pons very close to the middle cerebellar peduncle. Blood supply The middle cerebellar peduncle is supplied by the anterior inferior cerebellar artery (AICA), as well as smaller branches from the basilar artery. == Clinical significance ==

Infarction of the anterior inferior cerebellar artery (AICA) can damage the middle cerebellar peduncle. == Additional images ==
