Portion of the mesoderm that gives rise to the notochord and prechordal plate.
extraembryonic mesoderm
Mesoderm lying outside the embryo proper and involved in the formation of amnion, chorion, yolk sac, and body stalk.
intermediate mesoderm
Mesoderm lying between somite and lateral mesoderm, and giving rise to embryonic and definitive kidneys and their ducts.
lateral mesoderm
Unsegmented mesoderm lying lateral to the intermediate mesoderm. In it develops a cavity (coelom), separating it into layers (somatic and splanchnic mesoderm).
Synonym: hypomereparaxial mesoderm
Mesoderm lying immediately lateral to the neural tube and notochord.
somatic mesoderm
The outer layer of the lateral mesoderm. It becomes intimately associated with the ectoderm, forming the somatopleure, from which the ventral and lateral walls of the embryo develop.
splanchnic mesoderm
The inner layer of the lateral mesoderm. It becomes intimately associated with the endoderm, forming the splanchnopleure, from which the gut and the lungs and their coverings arise.
