Middle cerebellar peduncle

The middle cerebellar peduncles (brachia pontis) are paired structures (left and right) that connect the cerebellum to the pons and are composed entirely of centripetal fibers, i.e. incoming fibers. The fibers arise from the pontine nucleus to the opposite hemisphere of the cerebellar cortex. The fibers are arranged in three fasciculi: superior, inferior, and deep.Scheme showing the connections of the several parts of the brain.Superficial dissection of brain-stem.
