Study Notes
Autonomic Nervous System
- The component of the nervous system that operates without conscious control is the Autonomic Nervous System (ANS).
- The part of the body that contains receptors such as baroreceptors and chemoreceptors for the ANS is the Carotid Artery and Aorta.
Functions of the Autonomic Nervous System
- The part of the nervous system that primarily controls and modulates the functions of visceral organs like heart rate and blood pressure is the Autonomic Nervous System (ANS).
- The ANS is responsible for controlling involuntary actions such as heart rate, digestion, breathing, and blood pressure.
Divisions of the Autonomic Nervous System
- The division of the autonomic nervous system involved in the 'fight or flight' response is the Sympathetic Nervous System (SNS).
- The part of the autonomic nervous system responsible for controlling functions during rest and digest activities is the Parasympathetic Nervous System (PNS).
