The material for the study was taken from 2 spinal cords of sexually mature horses. Preparations obtained from this material were stained according to Nissl and with the use of cresyl violet. The nucleus dorsalis of the horse extends from the 8th cervical neuromere to the 3rd lumbar neuromere of the spinal cord. The cells which form this nucleus lie in the grey matter of the spinal cord, dorsolaterally of the central canal. The nucleus dorsalis is made out of large and medium-size round and oval cells. The characteristic feature of the structure and configuration of this nucleus in the horse is the occurrence of numerous discontinuities over a considerable part of its length. The nucleus is continuous only over a short distance contained between Th17 and 2/3 of the anterior L2. The nucleus dorsalis shows great variation with regard to the number of cells which form it in the individual neuromeres of the spinal cord. In this respect, the best developed segment of the nucleus in the horse is contained between Th17 and L2.
本研究材料取自2条性成熟马的脊髓。用此材料制作的标本按尼氏染色法并用甲酚紫进行染色。马的背核从脊髓的第8颈神经节延伸至第3腰神经节。构成该核的细胞位于脊髓灰质中，中央管的背外侧。背核由大、中型圆形和椭圆形细胞组成。马的这个核的结构和形态的特征是在其相当长的一段长度上存在许多间断。该核仅在胸17和腰2前部的2/3之间的短距离内是连续的。背核在脊髓各个神经节中构成它的细胞数量方面表现出很大差异。在这方面，马的核发育最完善的节段位于胸17和腰2之间。
