The anatomical division is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system includes the cerebrum, cerebellum, brainstem, spinal cord, thalamus, subthalamus, and basal ganglia. The peripheral nervous system includes the spinal nerves, cranial nerves, and sensors.
The functional divisions of the nervous system are composed of the autonomic nervous system (ANS) and the somatic nervous system.

The somatic nervous system is the voluntary component of the nervous system.
