endoderm

(ĕn`dədûrm'), in biology, inner layer of tissue formed in the gastrula stage of the developing embryo. At the end of the blastula stage, cells of the embryo are arranged in the form of a hollow ball. Cell movement results in an invagination of the bottom region, or vegetal hemisphere, of the embryo so that it resembles a double-walled cup. The inner layer of the cup is the endoderm; the outer layer is the ectodermectoderm,
layer of cells that covers the surface of an animal embryo after the process of gastrulation has occurred. This outer layer, together with the endoderm, or inner layer, is present in all early embryos.

Endoderm

(1) The internal layer of the embryo of multicellular animals in the gastrular stage (the internal germ layer). In the process of development, the endoderm forms the wall of the archenteron, which forms the mucosa of the entire intestine and the glands connected with the intestinal tract, including the liver and pancreas. In fishes, the endoderm forms the swim bladder and the internal gills, while in higher vertebrates it forms the lungs. In chordates, the endoderm and organs formed from it exert an inductive influence on the development of the chordamesoderm and on certain body parts formed from the ectoderm, including the mouth, anus, gill slits, and external gills. In turn, the endoderm and organs formed from it typically require interaction with materials originating from the ectoderm and mesoderm.

(2) The internal layer of the body wall in coelenterates.

endoderm

[′en·dō‚dərm] (embryology) The inner, primary germ layer of an animal embryo; sometimes referred to as the hypoblast. Also known as entoderm; hypoblast.

endoderm

[en´do-derm] the innermost of the three primary germ layers of the embryo; from it are derived the epithelium of the pharynx, respiratory tract (except the nose), digestive tract, bladder, and urethra. Called also endoblast, entoderm, entoblast, and hypoblast.

en·do·derm

(en'dō-dĕrm), The innermost of the three primary germ layers of the embryo (ectoderm, mesoderm, endoderm); from it is derived the epithelial lining of the primordial gut and the epithelial component of the glands and other structures (for example, lower respiratory system) that develop as outgrowths from the gut. Synonym(s): entoderm [endo- + G. derma, skin]

endoderm

(ĕn′də-dûrm′) also

entoderm

(ĕn′tə-)n. The innermost of the three primary germ layers of an animal embryo, developing into the gastrointestinal tract, the lungs, and associated structures. Also called hypoblast.

en′do·der′mal adj.

en·do·derm

(en'dō-dĕrm) The innermost of the three primary germ layers of the embryo (ectoderm, mesoderm, endoderm); from it are derived the epithelial lining of the primordial gut and the epithelial component of the glands and other structures (e.g., lower respiratory system) that develop as outgrowths from the gut tube.
Synonym(s): entoderm, hypoblast. [endo- + G. derma, skin]

endoderm

The innermost of the three primary germ layers of an EMBRYO. The endoderm develops into the INTESTINAL TRACT and its associated structures and glands, the respiratory and urinary tracts and most of the endocrine glands. See also MESODERM and ECTODERM.

endoderm

endoblast

the embryological germ layer in animals that gives rise to the gut system and its association organs. It arises initially as a result of GASTRULATION from cells which have moved in from the surface of the BLASTULA. Compare ECTODERM and MESODERM.
