The two divisions of the autonomic nervous system are:
- Sympathetic Nervous System
- Parasympathetic Nervous System
These divisions work together to regulate involuntary body functions, including heart rate, digestion, and respiratory rate. The sympathetic nervous system is often associated with the "fight or flight" response, while the parasympathetic nervous system is associated with "rest and digest" functions.
The other options you mentioned, "Peripheral" and "Somatic," are not divisions of the autonomic nervous system. The peripheral nervous system encompasses both the autonomic and somatic nervous systems. The somatic nervous system controls voluntary movements and the relay of sensory information.
