Which two parts make up the peripheral nervous system?

The correct answer identifies the two components of the peripheral nervous system, which are the somatic and autonomic nervous systems. The somatic nervous system is responsible for voluntary movements, controlling skeletal muscles and facilitating sensory input from the body to the central nervous system. In contrast, the autonomic nervous system regulates involuntary bodily functions such as heartbeat, digestion, and respiratory rate, operating without conscious control.

Understanding these two subdivisions is crucial because they illustrate the functionality of the peripheral nervous system in both conscious and unconscious activities, highlighting how it integrates sensory input and motor control throughout the body.

Other options might refer to related concepts, but they do not accurately encompass the complete classification of the peripheral nervous system as this answer does.
