Detailed explanation-1: -The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord carries nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body.
Detailed explanation-2: -The three primary roles of the spinal cord are to send motor commands from the brain to the body, send sensory information from the body to the brain, and coordinate reflexes.
Detailed explanation-3: -The peripheral nervous system is the network of nerves strands that branch off from the left and right sides of the spinal cord through openings between each vertebra on the spinal canal. These nerve pairs spread throughout your body to deliver commands from your brain and spinal cord to and from parts of your body.
