In the verterbrate embryo, as the primitive streak is regressing the '''paraxial mesoderm''' divides into blocks of cells called '''somites'''. These divisions can be seen either side of the notochord. Somites are transient structures that will give rise to cells of the vertebrae and ribs, dermis of the dorsum, skeletal muscle of the body wall, back and limbs. Somites begin to develop at the anterior of the embryo first, and appear at regular intervals.
