Spinal cord, light micrograph

Description: Spinal cord. Light micrograph of a section through part of the spinal cord, showing grey matter (orange) and white matter (light brown). The spinal cord is a downwards extension of the brain, and is responsible for relaying sensory and motor signals between the brain and the body. The grey matter consists of neuron (nerve cell) bodies, unmyelinated nerve fibers, support cells and capillaries. White matter consists solely of myelinated nerve fibers. Myelin is an insulating fatty layer that surrounds some nerve fibers. Its presence increases the speed at which nerve impulses travel. Magnification: X85 when printed at 10 centimeters wide.
