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 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.

Detailed explanation-3: -The brainstem connects the brain and the spinal cord. It is made up of the pons, the medulla (meh-DULL-uh), and the midbrain. These parts work together to control and coordinate the messages going in and out of the brain.

Detailed explanation-4: -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-5: -(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).
