In the verterbrate embryo, the anterior of the embryo also begins to form into blocks of cells known as [[Developmental Biology - Somite Development - Anatomy & Physiology|somites]]. 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; they originate from the section of mesoderm known as [[Developmental Biology - Gastrulation - Anatomy & Physiology|paraxial mesoderm]].

The mesoderm also gives rise to the [[Developmental Anatomy of the Kidneys and Urinary Tract - Anatomy & Physiology|urinary system]] and some parts of the reproductive system; these develop from intermediate mesoderm. Lateral plate mesoderm differentiates into the [[Developmental Anatomy of the Heart - Anatomy & Physiology|heart]], the vascular system, the [[Developmental Biology - Limb Development - Anatomy & Physiology|limbs]], and the tissue around alimentary canal, or digestive system.
