Nerves are located throughout the body, extending from the central nervous system (CNS) to all parts of the body. The CNS consists of the brain and spinal cord, while the peripheral nervous system (PNS) is made up of nerves that branch off from the spinal cord.
- Cranial Nerves: Twelve pairs of cranial nerves originate from the brain and control functions like smell, sight, hearing, taste, facial movement, and eye movement.
- Spinal Nerves: Thirty-one pairs of spinal nerves emerge from the spinal cord and are responsible for transmitting signals to and from the body. These nerves control sensations, movement, and autonomic functions like breathing and digestion.
The PNS plays a vital role in connecting the CNS to the rest of the body, allowing for communication and coordination of various functions.
