NEET PG DENTAL EXAM

Detailed explanation-1: -The cerebral peduncles are the two stalks that attach the cerebrum to the brainstem. They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) nerve tracts that run to and from the cerebrum from the pons.

Detailed explanation-2: -The two systems connect at the Circle of Willis (green circle). The vertebral arteries supply the cerebellum, brainstem, and the underside of the cerebrum. After passing through the skull, the right and left vertebral arteries join together to form the basilar artery.

Detailed explanation-3: -Cerebellar peduncles connect the cerebellum to the brain stem. 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.

Detailed explanation-4: -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.
