The part of the nervous system that is outside the brain and spinal cord is called the peripheral nervous system. It consists of nerves that connect the central nervous system (brain and spinal cord) to the rest of the body. The peripheral nervous system includes sensory nerves, motor nerves, and autonomic nerves.
On the other hand, the part of the nervous system that includes the brain and spinal cord is known as the central nervous system. This is where most of the body's processing and coordination takes place. The brain is responsible for functions like thinking, memory, and emotions, while the spinal cord helps transmit messages between the brain and the body.
In summary:
1. Peripheral nervous system: outside the brain and spinal cord, connects the central nervous system to the body, includes sensory, motor, and autonomic nerves.
2. Central nervous system: includes the brain and spinal cord, responsible for processing and coordination of bodily functions like thinking, memory, and transmitting messages.
