Question

Does cerebral hemisphere covers brain stem completely

Answer 1

Evolutionarily, the brainstem is the most ancient part of the brain. Structurally, it can be divided into the medulla oblongata, pons, and midbrain.

Answer 2

The brain stem connects the brain with the spinal cord. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing. The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges.
