Superior cerebellar peduncle
A
Ridges of cerebellar cortex
B
White matter of the cerebellum
C
Connect the cerebellum to the pons
D
Connect the cerebellum to the midbrain
Explanation: 

Detailed explanation-1: -The superior cerebellar peduncles, also known as the brachium conjunctivum, are paired white matter fiber tracts that connect the cerebellum with the midbrain. The superior cerebellar peduncle contains vital afferent and efferent fibers including cerebellothalamic, cerebellorubral and ventrospinocerebellar tracts.

Detailed explanation-2: -The middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum, which is entirely afferent to the cerebellum. The rostral cerebellar peduncle connects the cerebellum with the mesencephalon and contains mainly efferent processes passing out of the cerebellum.

Detailed explanation-3: -Rostral cerebellar peduncle (brachium conjunctivum) connects the cerebellum to the midbrain and forebrain. Efferent fibers in the peduncle decussate immediately in the midbrain and thus they affect contralateral motor centers.

Detailed explanation-4: -The superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the midbrain.

Detailed explanation-5: -Cerebellar peduncles are the structure connecting the cerebellum to the brain stem and the cerebrum. There exist three cerebellar peduncles. The superior cerebellar peduncle (SCP) involves vestibular sense and proprioception connecting to the thalamocortical pathway.
