    • n mesoderm The middle germinal layer of the three-layered embryo of any metazoic animal, lying between the endoderm and the ectoderm. The term is used synonymously with mesoblast, the correlation being endoderm, mesoderm, and ectoderm; hypoblast, mesoblast, and epiblast; or mucous, vascular, and serous layers. Most of the body of every metazoan animal is derived from the mesoderm. When the embryo becomes four-layered, as it usually does, this state results from the splitting of the mesoderm into an inner visceral and an outer parietal layer, called respectively splanchnopleural and somatopleural, or involuntomotory and voluntomotory.
    • n mesoderm In botany, the middle layer of tissue in the shell of the spore-case of an urn-moss.
