Definition

Rexed’s laminae is an architectural classification of the structure of the spinal cord, based on the cytological features of the neurons in different regions of the gray substance described by the Swedish Anatomist B. Rexed. It consists of nine laminae (I–IX) that extend throughout the cord, roughly paralleling the dorsal and ventral columns of the gray substance, and a tenth region (lamina X) that surrounds the central canal and consists of the dorsal and ventral commissures and the central gelatinous substance. Laminae I and II are often referred to as the superficial part of the dorsal horn.
