Verified step by step guidance

1. Step 1: Understand the basic divisions of the nervous system. The nervous system is primarily divided into the central nervous system (CNS) and the peripheral nervous system (PNS).
2. Step 2: Recall that the central nervous system (CNS) consists of the brain and spinal cord, which are responsible for processing and integrating information.
3. Step 3: Recognize that the peripheral nervous system (PNS) includes all the nerves outside the brain and spinal cord, connecting the CNS to the rest of the body.
4. Step 4: Identify the somatic nervous system as a subdivision of the PNS that controls voluntary movements by transmitting signals to skeletal muscles.
5. Step 5: Note that the autonomic nervous system is another subdivision of the PNS, responsible for regulating involuntary functions like heart rate and digestion.
