PATHOLOGY

Detailed explanation-1: -The brainstem (brain stem) is the distal part of the brain. It contains the midbrain (mesencephalon), the pons and the medulla oblongata. Brainstem does not include cerebellum which is part of the hindbrain .

Detailed explanation-2: -The cerebrum, which forms the major portion of the brain, is divided into two major parts: the right and left cerebral hemispheres. The cerebrum is a term often used to describe the entire brain. A fissure or groove that separates the two hemispheres is called the great longitudinal fissure.

Detailed explanation-3: -Midbrain: The top part of the brainstem is crucial for regulating eye movements. Pons: The middle portion of the brainstem coordinates facial movements, hearing and balance. Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.
