Gastrula: that embryonic stage resembling a sac, with an outer layer of epiblastic cells and an inner layer of hypoblastic cells.
The hypoblastic notochord is early embraced by a mesoblastic sheath derived from the protovertebrae.
The liver and other digestive glands are first formed, like the lungs, as hollow outgrowths, and their lining is therefore hypoblastic.
Just as the yolk cells of the frog form the ventral wall of the intestine, so nuclei appear along the upper side of the yolk of the fowl, where some protoplasm still exists, and give rise to the ventral hypoblastic cells.
By conceiving a gradually increasing amount of yolk in the hypoblastic cells in the ventral side of the archenteron, the substantial identity of the gastrula stage in the three types, which at first appear so strikingly different, will be perceived.
These malformations are associated chiefly with imperfect development of the visceral or branchial arches and clefts, or of the hypoblastic diverticula from which the thyreoid and thymus glands are formed.
The _lateral fistula of the neck_ -- formerly described as a branchial fistula -- according to Weglowski, usually takes origin from the remains of the hypoblastic diverticulum, which arises from the pharyngeal part of the third visceral cleft and extends downwards to form the thymus gland.

There is no evidence that mesoblastic tissues can be converted into those of the epiblastic or hypoblastic type, or vice versa_. "[
