What are the two divisions of the nervous system?

The correct answer identifies the two main divisions of the nervous system as the central nervous system and the peripheral nervous system.

The central nervous system (CNS) comprises the brain and spinal cord, which serve as the control center for processing information and coordinating responses. It interprets sensory information, generates thoughts, and initiates movements.

The peripheral nervous system (PNS) consists of all the nerves that branch out from the CNS and extend to the rest of the body. It connects the CNS to limbs and organs, facilitating communication between the brain, spinal cord, and the rest of the body. This division is further subdivided into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which controls involuntary functions.

Understanding this division is crucial for fitness professionals, as it lays the foundation for knowledge about how the body responds to exercise, adapts to stressors, and maintains homeostasis.
