Somitogenesis
Somitogenesis is the process by which somites form. Somites are bilaterally paired blocks of mesoderm that form along the anterior-posterior axis of the developing embryo in segmented animals. In vertebrates, somites give rise to skeletal muscle, cartilage, tendons, endothelial cells, and dermis.
