The central nervous system consists of the and , and receives input from sensory neurons and directs the activities of motor neurons that innervate muscles and glands.

Central Nervous System (CNS): This consists of the brain and spinal cord. The brain is the control center, responsible for processing information, making decisions, and coordinating various functions. The spinal cord acts as a conduit, transmitting signals between the brain and the rest of the body.Peripheral Nervous System (PNS): This includes all the nerves outside the CNS. The PNS is further divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and sensory information, while the autonomic nervous system regulates involuntary processes like heart rate, digestion, and respiratory rate.

The nervous system that includes all of the neurons, nerves, ganglia, and plexuses outside the CNS is the nervous system.

The 3 main roles of the nervous system are to:Receive motor input, integrate the information and generate sensory outputReceive sensory input, integrate the information and generate motor outputAllow us to move, see and hear.Allow us to see, think and feel

The peripheral nervous system consists of the nerves, which control the head, neck, and facial regions, and nerves, which control the rest of the body.
