Approximately 18 inches (45 cm) long, the human spinal cord is the body’s major neural tract, a thin, tubular bundle of nerves that is enclosed in and protected by the bony vertebral column. Together, the spinal cord and brain compose the central nervous system. Injury to the spinal cord may result in a loss of communication between the brain and sections of the spinal cord, causing paralysis, loss of sensation, or weakness. From what part of the brain does the spinal cord extend? Discuss
