Rexed laminae

Rexed laminae
an architectural scheme used to classify the structure of the spinal cord, based on the cytological features of the neurons in different regions of the gray substance. 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 (area X) that surrounds the central canal and consists of the dorsal and ventral commissures and the central gelatinous substance.

Rexed laminae in a cross-section of the spinal cord at approximately the level of the seventh cervical vertebra (C7).
