Spinal cord, the great nervous cord extending backward from the brain along the dorsal side of the spinal column of a vertebrate animal, and usually terminating in a threadlike appendage called the filum terminale; the spinal, or vertebral, marrow; the myelon. The nervous tissue consists of nerve fibers and nerve cells, the latter being confined to the so-called gray matter of the central portions of the cord, while the peripheral white matter is composed of nerve fibers only. The center of the cord is traversed by a slender canal connecting with the ventricles of the brain. [1913 Webster]
