Comparison of the Central and Peripheral Nervous Systems
The nervous system is broadly divided into two main parts. The Central Nervous System (CNS) consists of the brain and spinal cord, serving as the primary control center. In contrast, the Peripheral Nervous System (PNS) is composed of all the nerves that branch out from the CNS, connecting it to the rest of the body, including limbs and organs.

Comparison of the Central and Peripheral Nervous Systems

This reflex action involves sensory information traveling to the spinal cord, which then sends a command back to the muscles in the arm. How does this scenario illustrate the distinct functions of the two major subdivisions of the nervous system?
