Definition

Muhammad A. Javaid

Spinal area X (Rexed lamina X) refers to the gray matter surrounding the central canal of the spinal cord, also known as the central intermediate substance of the spinal cord. It comprises the posterior (dorsal) and anterior (ventral) gray commissures, located behind and in front of the central canal, respectively. The anterior gray commissure links the ventral horns of gray matter on the right and left sides of the spinal cord, while the posterior gray commissure connects the dorsal horns of gray matter between the two spinal halves.
