Spinal Cord: the Body's Vital "Control Center"

The most important function of the spine is to protect the spinal cord, the vital control center without which the musculoskeletal system and other vital organs of the body could not operate. Not even the most sophisticated computer system can match the performance of this cord of nerve tissue. Less than 12 feet long, little more than 3-inch in diameter and weighing about an ounce . . .

the spinal cord is the calculator and relay center of a vast and intricate miracle network of nerves that reach into every part of the human body.

The spinal cord passes through the canal formed by the vertebral arches, continuous with and extending downward from the base of the brain (medulla oblongata). At the first lumbar vertebra, the single cord ends in a number of delicate filaments or threads that extend to the end of the spine and fasten the spinal cord to the coccyx. Cerebrospinal fluid maintains pressure in the cord, which is insulated from the bony canal by three layers of coverings called meninges.
