What are the two main parts of the nervous system?

• A. CNS and PNS
• B. Brain and heart
• C. Spinal Cord and muscles
• D. Nerves and sensory organs

Answer: (A)

The two main parts of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, which serve as the control center for processing information and coordinating responses. It is responsible for interpreting sensory input and initiating appropriate actions. In contrast, the PNS includes all the nerves that branch off from the spinal cord and extend to other parts of the body. This system acts as a communication network that sends information to and from the CNS, allowing signals to reach muscles and organs. Understanding the distinction between these two systems is crucial in the study of animal management and biological systems, as each part has distinct functions and works together to maintain homeostasis and respond to environmental changes.
