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]

(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.

endoderm

[en′dədurm]
Etymology: Gk, endon + derma, skin
(in embryology) the innermost of the cell layers that develop from the embryonic disk of the inner cell mass of the blastocyst. From the endoderm arises the epithelium of the trachea, bronchi, lungs, GI tract, liver, pancreas, urinary bladder, anal canal, pharynx, thyroid, tympanic cavity, tonsils, and parathyroid glands. The endoderm thus comprises the lining of the cavities and passages of the body and the covering of most of the internal organs. Compare ectoderm, hypoblast, mesoderm.

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

or

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.

endoderm

inner layer of the three primary germ layers forming an embryo; gives rise to gut and associated structures
