Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Structures called ____ connect the cerebellum to the brainstem and allow communication between the cerebellum and other parts of the CNS.
A
Vermis
B
Funiculi
C
Peduncles
D
Commissure
Explanation: 

Detailed explanation-1: -The cerebellum is connected to the brainstem by three pairs of cerebellar peduncles: the superior peduncle with the midbrain, the middle peduncle with the pons, and the inferior peduncle with the medulla oblongata.

Detailed explanation-2: -The cerebellum contains a cerebellar circuit, using Purkinje cells and cerebellar peduncles to communicate to other parts of the brain. The superior cerebellar peduncle is composed of white matter that connects the cerebellum to the midbrain and allows for coordination in the arms and legs.

Detailed explanation-3: -The cerebellum attaches to the brainstem by three groups of nerve fibers called the superior, middle and inferior cerebellar peduncles, through which efferent and afferent fibers pass to connect with the rest of the nervous system.

Detailed explanation-4: -Brainstem. The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.

Detailed explanation-5: -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.
