Question 1

How many cerebellar peduncles do we have?

Answer 1

Cerebellar peduncles connect the cerebellum to the brain stem.[1] 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.

Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.

Inferior cerebellar peduncle is a thick rope-like strand that occupies the upper part of the posterior district of the medulla oblongata.
