Pertaining to the mesoderm.


(mes'o-derm) [? + derma, skin]
A primary germ layer of the embryo lying between ectoderm and endoderm. From it arise all connective tissues; muscular, skeletal, circulatory, lymphatic, and urogenital systems; and the linings of the body cavities. See: ectoderm; endodermmesodermicmesodermal, adjective

axial mesoderm

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: hypomere

paraxial 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.
