[Structure and topography of the nucleus proprius cornus dorsalis of the spinal cord of horses]

The studies performed on spinal cords of two horses revealed that cells of the nucleus of the own dorsal horn are present in all segments of lumbo-sacral part of the spinal cord. The nucleus is composed of two parts: basal and marginal. Basal part is composed of large and medium size cells situated in 2/3 of the lower part of the grey substance of the dorsal horn. The marginal part of the described nucleus is composed of elongated and spindle shaped cells situated along the dorsal margine of the grey substance of the dorsal horn. Continuity of the nucleus in lumbo-sacral part of the spinal cord was conserved and only constrictions due to a various number of cells forming the nucleus in individual segments of spinal cord were noted.
