Two medullae oblongatae of horses were cut into 15 microns cross-sections and stained according to the modified method of Nissel. The lateral motor nucleus lies in the lateral and median part of the ventral column of spinal cord grey matter. It adjoins medially nucleus motorius medialis of the spinal ventral column. Cells of this nucleus occur both along the whole lumbar and sacral segment of the spinal cord. In the lateral motor nucleus three cell groups are distinguished - median, basal and lateral. The latter is divided in some segments into subgroups - dorsal and ventral. Along the nucleus quite numerous constrictions and intervals are found, which are caused by various numbers of cells in particular cross-sections. Nucleus motorius lateralis is formed mainly of large and medium multipolar or single spindle cells.
将两匹马的延髓切成15微米的横切片，并按照改良的尼氏方法进行染色。外侧运动核位于脊髓灰质腹侧柱的外侧和中间部分。它在内侧与脊髓腹侧柱的内侧运动核相邻。该核的细胞沿脊髓的整个腰段和骶段均有分布。在外侧运动核中可区分出三个细胞群——中间群、基部群和外侧群。外侧群在某些节段又分为背侧和腹侧亚群。沿该核发现有相当多的缩窄和间隙，这是由特定横切片中细胞数量的不同所致。外侧运动核主要由大、中型多极或单极梭形细胞构成。
