Gastrulae
(gcide) | Gastrula \Gas"tru*la\, n.; pl. Gastrul[ae][NL., dim. fr. Gr. ?
the stomach.] (Biol.)
An embryonic form having its origin in the invagination or
pushing in of the wall of the planula or blastula (the
blastosphere) on one side, thus giving rise to a
double-walled sac, with one opening or mouth (the blastopore)
which leads into the cavity (the archenteron) lined by the
inner wall (the hypoblast). See Illust. under Invagination.
In a more general sense, an ideal stage in embryonic
development. See Gastr[ae]a. -- a. Of or pertaining to a
gastrula.
