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.

The knowledge we possess of any part is made up of the numberless impressions from without which affect its sensitive surfaces, and which are transmitted through its nerves to the spinal nerve-cells, and through them, again, to the brain.
