A spinal nerve is a nerve that originates from the spinal cord and extends through openings in the vertebrae to innervate various regions of the body. They are responsible for transmitting sensory information from the body to the spinal cord and brain, as well as carrying motor signals from the brain to the muscles and organs. The spinal nerves play a vital role in coordinating movement, sensation, and autonomic functions throughout the body.
