Question

what are the 2 major divisions of the peripheral nervous system (pns)?
○ peripheral & central
○ brain & spinal cord
○ sensory & motor
○ somatic & autonomic

Explanation:

To determine the correct answer, we analyze each option:

• "Peripheral & Central" is incorrect because the central nervous system (CNS) and peripheral nervous system (PNS) are the two main divisions of the entire nervous system, not just the PNS.
• "Brain & Spinal Cord" is incorrect as these are the components of the central nervous system (CNS), not the PNS.
• "Sensory & Motor" is a way to classify neurons or functions, but not the major divisions of the PNS.
• "Somatic & Autonomic" is correct. The peripheral nervous system (PNS) is divided into the somatic nervous system (which controls voluntary movements and sensory input from the body) and the autonomic nervous system (which controls involuntary functions like heart rate, digestion, etc.).

Answer:

D. Somatic & Autonomic
