Answer:The nervous system is a complex network that plays a crucial role in controlling and coordinating various functions in the body. It consists of two main parts:1. **Central Nervous System (CNS)**: This includes the brain and spinal cord. The CNS acts as the command center, processing information and sending signals to the rest of the body to regulate thoughts, movements, and feelings.2. **Peripheral Nervous System (PNS)**: This system comprises a network of nerves that branch out from the spinal cord. It relays information between the CNS and the rest of the body, including organs and limbs, allowing for sensory input and motor output.The nervous system is essential for regulating vital functions like heartbeat, breathing, and digestion, as well as enabling sensations and body movements<sup>1</sup> <sup>2</sup> <sup>3</sup>.
