AP PSYCHOLOGY

Detailed explanation-1: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

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 autonomic nervous system manages body processes you don’t think about. Those processes include heartbeat, blood pressure, digestion and more.

Detailed explanation-5: -A part of the peripheral nervous system called the autonomic nervous system controls many of the body processes you almost never need to think about, like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system.
