Which subdivision of the nervous system regulates involuntary actions?

The autonomic nervous system handles actions that happen without our conscious control, regulating activities of the organs, glands, and smooth or cardiac muscle. It keeps things like heart rate, digestion, and pupil size functioning smoothly and automatically. It has two main branches—sympathetic, which prepares the body for action, and parasympathetic, which promotes rest and digestion—working together to maintain balance. The central nervous system (brain and spinal cord) processes information but does not alone regulate these involuntary functions, and the somatic nervous system controls voluntary movements and conscious sensation. The peripheral nervous system includes nerves outside the brain and spinal cord, but the specific division responsible for involuntary regulation is the autonomic nervous system.
