Detailed explanation-1: -Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.

Detailed explanation-2: -The brain stem is the lower part of the brain that’s connected to the spinal cord (part of the central nervous system in the spinal column). The brain stem is responsible for regulating most of the body’s automatic functions that are essential for life. These include: breathing.

Detailed explanation-3: -The brain stem, at the base of the brain, communicates with the hypothalamus to control the transitions between wake and sleep. (The brain stem includes structures called the pons, medulla, and midbrain.)

Detailed explanation-4: -It is responsible for many vital functions of life, such as breathing, consciousness, blood pressure, heart rate, and sleep. The brainstem contains many critical collections of white and grey matter. The grey matter within the brainstem consists of nerve cell bodies and forms many important brainstem nuclei.

Detailed explanation-5: -Medulla. At the bottom of the brainstem, the medulla is where the brain meets the spinal cord. The medulla is essential to survival. Functions of the medulla regulate many bodily activities, including heart rhythm, breathing, blood flow, and oxygen and carbon dioxide levels.
