Triploblasty is a condition of the gastrula in which there are three primary germ layers: the ectoderm, mesoderm, and endoderm. Germ cells are set aside in the embryo at the blastula stage, and are incorporated into the gonads during organogenesis. The germ layers form during the gastrulation of the blastula.

2022年6月16日 · Triploblastic means having three primary germ layers, particularly ectoderm, mesoderm and endoderm. All higher and intermediate animals (i.e. from flatworms to humans develop from a triploblastic embryo, in contrast to other organisms (e.g. cnidaria) that develop from a diploblastic embryo.

The meaning of TRIPLOBLASTICA is animals having three germ layers —used when these are held to form a natural group comprising the worms and all higher forms.

…defined tissues and organs) are triploblastic (i.e., their members have three layers of cells), with the third cellular layer, called the mesoderm, developing between the endoderm and ectoderm. At its simplest, the mesoderm provides a network of packing cells around the animal’s organs; this is probably best exhibited in the…

Triploblastica refers to a group of animals that develop three primary germ layers during embryogenesis: the ectoderm, mesoderm, and endoderm. This triploblastic condition is a characteristic of more complex organisms, including all bilaterally symmetrical animals.

The new Bilateria includes the Cnidaria and the former Bilateria, now dubbed as Triploblastica, the latter split into a paraphyletic ‘Acoelomorpha’ (Acoela and Nemertodermatida) and the rest of the bilaterians or Nephrozoa. Note that the LCBA for cnidarians+Triploblastica is less complex than the ancestor for Triploblastica.
