During embryonic development, many animals form a number of temporary structures along their anterior-posterior axis-somites. Cells in somites differentiate into sclerotome, which gives rise to vertebral column, dermatome, which gives rise to dermis, and myotome, which gives rise to skeletal muscle.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构－体节，随着胚胎的继续发育每个体节分化成为生骨区、生皮区和生肌区，继而生成各种组织。
