-
The germinal, or blastodermic membrane, or vesicle; a membranous bag formed in the fecundated ovum, consisting of segmentation spherules (blastomeres) pressed away from the center by the accumulation of blastochyle; the rudimentary structure from which the embryo is formed. At first it is a simple layer; after the formation of the primitive streak, it consists of two layers, the epiblast (ectoderm) externally and the hypoblast (entoderm) internally; after the formation of the medullary plates and the notochord, a third layer, the mesoblast (mesoderm), forms between the two. See epiblast, hypoblast, and mesoblast.
