The spinal cord lies in which part of the human body?

The spinal cord is a complex cylinder of nerves that starts at the base of the brain and runs down the vertebral canal to the backbone.

Like the brain, the spinal cord consists of gray matter and white matter. The butterfly-shaped center of the cord consists of gray matter. The front “wings” (called horns) contain motor nerve cells, which transmit information from the brain or spinal cord to muscles, stimulating movement. The back horns contain sensory nerve cells, which transmit sensory information from other parts of the body through the spinal cord to the brain. The surrounding white matter contains columns of nerve fibers that carry sensory information to the brain from the rest of the body and columns that carry impulses from the brain to the muscles.
