One of the three primary germ layers; the layer on the undersurface of the embryonic disc; gives rise to the epithelia and glands of the digestive system, the respiratory system, and portions of the urinary system.
(Greek, endo = inside + derma = skin) The layer (of the 3 germ cell layers) which form the epithelial lining of the gastrointestinal tract (GIT) and accessory organs of GIT in the embryo. ( More? Week 3 Notes)
Gr. endon: within + derma: skin] • The innermost of the three embryonic tissue layers first delineated during gastrulation. Gives rise to the digestive and respiratory tracts and structures associated with them.
The lower, inner of the three primitive germ layers of the embryo that will give rise to the epithelial layers of the lungs and bronchi, pharynx, gastrointestinal tract, liver, pancreas, and urinary bladder.
The "lower" layer of the embryo, as the inner cell mass forms a circular disk two cells thick; with further embryonic development it gives rise to the digestive tract and its glands. Synonym: hypoblast. See also: ectoderm See also: mesoderm
the inner of the three cell layers which form, as the clump of early embryonic cells begins to differentiate. The endoderm will form the gut system and its associated organs. The other two layers are the mesoderm and the ectoderm. www.dental-site.itgo.com/glossary.htm the inner layer of cells, which develops into digestive and respiratory systems.

Gr. endon - within; Gr. derma - skin, leather] The innermost germ layer of the embryo that develops during gastrulation. It will form the lining of the respiratory and digestive organs and their derivatives.
The inner layer of tissue formed in the gastrula stage of development. At the end of blastula, the cells are arranged in the form of a hollow ball. Cell movement during gastrulation results in an invagination so that the embryo comes to resemble a double-walled cup. The inner layer of the cup is the endoderm. Endodermal cells usually end up forming the gut, pharynx, liver, lungs, and similar structures.
