ANATOMY

Detailed explanation-1: -The somatic nervous system controls the skeletal muscles. The autonomic nervous system controls the involuntary actions of many internal organs.

Detailed explanation-2: -The medulla oblongata is the rod-shaped part of the brain which is seen below the cerebrum, located near the cerebellum of the brain. It controls involuntary actions like heartbeat and breathing.

Detailed explanation-3: -The hypothalamus is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control. The major pathway from the hypothalamus for autonomic control is the dorsal longitudinal fasciculus.

Detailed explanation-4: -The part of the nervous system that controls muscles of internal organs (such as the heart, blood vessels, lungs, stomach, and intestines) and glands (such as salivary glands and sweat glands).

Detailed explanation-5: -Although most of the autonomic nervous system responses are involuntary, they can integrate with the somatic nervous system, which is responsible for the voluntary movements.
