endoderm

[obophenotype-user]

Please add new synonyms:

"definitive endoderm" as a synonym of endoderm where applicable (as there is a separate lineage of endodermal cells which are extra-embryonic, i.e. contributing to the placenta).

"entoderm" is also frequently encountered as a synonym of endoderm; see http://www.merriam-webster.com/dictionary/entoderm

Modify the def of "abnormal endoderm development [MP:0001685]" to read as: SUGGESTED DEF: any abnormality in the formation of the innermost of the three primary germ layers of the embryo (the others being mesoderm and ectoderm) during gastrulation; endoderm gives rise to the epithelial lining of the gastrointestinal and respiratory tracts; the parenchyma of the tonsils, the liver, the thymus, the thyroid, the parathyroids, and the pancreas; the epithelial lining of the urinary bladder, urethra, and prostate; and the epithelial lining of the tympanic cavity, tympanic antrum, and auditory tube

New term:

absent endoderm DEF: absence of the innermost of the three primary germ layers of the embryo (the others being mesoderm and ectoderm) that is formed during gastrulation SYN: absent definitive endoderm SYN: absent entoderm

NOTE: There is already a term for abnormal anterior definitive endoderm morphology [MP:0008926]
