What is a primary function of the spinal cord, the long bundle of nerve tissue running through the vertebral column?

Explanation

The spinal cord is a long, cylindrical bundle of nerve tissue that runs through and is protected by the vertebral column, serving as the primary communication pathway relaying sensory and motor signals back and forth between the brain and the rest of the body. Beyond this important relay function, the spinal cord can also independently control certain rapid, automatic reflex actions, such as quickly pulling a hand away from a painful stimulus, without needing to wait for those signals to first travel all the way to the brain. Damage to the spinal cord can significantly disrupt this vital communication pathway, potentially resulting in varying degrees of paralysis or loss of sensation below the site of injury.
