Detailed explanation-1: -This bundle is called the cauda equina because it resembles a horse’s tail. The cauda equina carries nerve impulses, both motor and sensory, to and from the legs. Like the brain, the spinal cord consists of gray and white matter.
Detailed explanation-2: -The spinal cord is a tube-like structure filled with a bundle of nerves and cerebrospinal fluid, which protects and nourishes the cord. Other protectors of the spinal cord include linings called meninges and vertebral bones. The spinal cord is about an inch across at its widest point and about 18 inches long.
Detailed explanation-3: -(SPY-nul kord) A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones).
Detailed explanation-4: -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-5: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.
