Definition of Gastrula

Gastrula
Stomapoda Sto*map"o*da, n. pl. [NL. See Stoma, and -poda.] (Zo["o]l.) An order of Crustacea including the squillas. The maxillipeds are leglike in form, and the large claws are comblike. They have a large and elongated abdomen, which contains a part of the stomach and heart; the abdominal appendages are large, and bear the gills. Called also Gastrula, Stomatopoda, and Squilloidea.
gastrula
Planula Plan"u*la, n.; pl. Planul[ae]. [L., a little plane.] 1. (Biol.) In embryonic development, a vesicle filled with fluid, formed from the morula by the divergence of its cells in such a manner as to give rise to a central space, around which the cells arrange themselves as an envelope; an embryonic form intermediate between the morula and gastrula. Sometimes used as synonymous with gastrula.
Gastrula
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.
