MICROANATOMY

Detailed explanation-1: -It regulates vital functions, such as heartbeat and breathing.

Detailed explanation-2: -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. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-3: -Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).

Detailed explanation-4: -Your hypothalamus performs many of its “body balancing” jobs either by directly influencing the autonomic nervous system or by managing hormones. Your autonomic nervous system (bodily functions that work automatically) control several important functions, such as your heart rate and breathing (respiration).
