ep·i·blast

(ep'i-blast),
Gives rise to the ectoderm, mesoderm, and endoderm of the embryo proper.
[epi- + G. blastos, germ]

epiblast

/epi·blast/ (ep´ĭ-blast)
1. the upper layer of the bilaminar embryonic disc present during the second week; it gives rise to ectoderm.
3. ectoderm, except for the neural plate.epiblas´tic

epiblast

(ĕp′ə-blăst′)
n.
The outer layer of a blastula that gives rise to the ectoderm after gastrulation.

ep′i·blas′tic adj.

epiblast

[ep′iblast′]
Etymology: Gk, epi, upon, blastos, germ
the primordial outer layer of the blastocyst or blastula, before differentiation of the germ layers, that gives rise to the ectoderm and contains cells capable of forming the endoderm and mesoderm. See also ectoderm. epiblastic, adj.

ep·i·blast

(ep'i-blast)
The component of the bilaminar embryonic disc that gives rise to ectoderm and mesoderm. The mesoderm then displaces the hypoblast cells and forms the entodermal cell layer on its inner surface.
[epi- + G. blastos, germ]

epiblast

layer of cells roofing over the blastocoel in the avian embryo.
