How many components does the nervous system have?

The nervous system consists of two main components: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system includes the brain and spinal cord, which process information and coordinate responses. The peripheral nervous system comprises all the nerves outside the CNS, responsible for transmitting signals to and from different parts of the body and the environment.

Understanding this division is crucial for fields such as corrections and probation, as it can inform how individuals may react to stress, trauma, or rehabilitation programs. The knowledge about these two components allows professionals to better understand the physiological and psychological aspects of behavior and decision-making in their work with individuals in the justice system.
