gray columns

(redirected from columnae griseae)

gray col·umns

the three somewhat ridge-shaped masses of gray matter (anterior, posterior, and intermediate columns) that extend longitudinally through the center of each lateral half of the spinal cord; in transverse sections these columns appear as gray horns and are therefore commonly called anterior (ventral), posterior (dorsal), and lateral horns, respectively.
