Pontocerebellar fibers
Encyclopedia
The pontocerebellar fibers are fibers that run within the middle cerebellar peduncles
, from the pons
to the cerebellum
.
The term "corticopontocerebellar" is sometimes used to denote afferent signals from the cerebral cortex

Middle cerebellar peduncles
The middle cerebellar peduncles are composed entirely of centripetal fibers, which arise from the cells of the nuclei pontis of the opposite side and end in the cerebellar cortex; the fibers are arranged in three fasciculi, superior, inferior, and deep.* The superior fasciculus, the most...

Pons
The pons is a structure located on the brain stem, named after the Latin word for "bridge" or the 16th-century Italian anatomist and surgeon Costanzo Varolio .
