Verified step by step guidance
1
Understand that the nervous system is broadly divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
Recognize that the central nervous system includes the brain and spinal cord, which process information and coordinate activity.
Know that the peripheral nervous system consists of all the nerves outside the brain and spinal cord, responsible for transmitting signals to and from the CNS.
Combine these two components to see that the entire nervous system is a complex network involving both the CNS and PNS working together.
Therefore, the phrase that best describes the entire nervous system is one that acknowledges this complexity and inclusion of both central and peripheral parts.
