Lateral plate mesoderm differentiates into the [[Heart Development - Anatomy & Physiology|heart]], the [[Vascular Development - Anatomy & Physiology|vascular system]], the lymphatic system, the [[Limb Development - Anatomy & Physiology|limbs]], and the tissue and smooth muscle surrounding the alimentary canal, or digestive system.

The formation of bone, or [[Bone & Joint Development - Anatomy & Physiology|osteogenesis]] has several different origins - the skull develops at the junction of the neural plate and the epidermis, the limb skeleton develops from lateral plate mesoderm, and the axial skeleton develops from paraxial mesoderm. Both [[Bones and Cartilage - Anatomy & Physiology|bones]] and [[Bones_and_Cartilage_- Anatomy & Physiology#Structure_and_Function_of_Cartilage|cartilage]] continue to develop into several well differentiated types specific to their anatomical position and function.

The endoderm will form the lining of the [[Gut Development - Anatomy & Physiology|alimentary canal]] and the glandular structures that develop within it. Endoderm also develops into other digestive organs such as the [[Pancreas - Anatomy & Physiology#Development|pancreas]]; it also gives rise to non digestive structures such as the [[Thyroid Gland - Anatomy & Physiology#Embryological Origin|thyroid gland]] which is formed from a downgrowth of the pharyngeal endoderm of the developing tongue. Initially, the alimentary canal is supended within two compartments; further development alters this arrangement so that a single [[Peritoneal Cavity - Anatomy & Physiology#Development|peritoneal cavity]] is formed.
