PATHOLOGY

Detailed explanation-1: -The autonomic nervous system is the part of the nervous system concerned with the innervation of involuntary structures, such as the heart, smooth muscle, and glands within the body.

Detailed explanation-2: -Both involuntary and voluntary actions are controlled by the same parts of the brain. Hindbrain and midbrain control involuntary actions like salivation, vomiting, etc. All the body’s voluntary actions are controlled by the motor cortex in the frontal lobe of the cerebrum.

Detailed explanation-3: -The autonomic (ah-tuh-NOM-ik) nervous system controls processes that happen automatically (involuntarily), like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system.
