Archenteron

Archenteron [Gr. arche - primitive; Gr. enteron - intestine]. The gut cavity formed by gastrulation in metazoan embryos; formed by infolding of part of the outer surface of the blastula and opening to exterior via blastopore. Full article ...

archenteron - cavity formed during gastrulation by invagination of the vegetal plate cells (in sea urchin) or involution of cells at the blastoporal lip (in amphibians); it will become the interior of the primitive gut.

archenteron The endoderm-lined cavity formed during the gastrulation process that develops into the digestive tract of an animal.

archenteron The main cavity of an embryo in the gastrula stage; it is lined with endoderm and represents the future digestive cavity. archinephric archi = beginning, original; nephros = kidney.

However, in protostomes the initial opening (the archenteron) develops into the mouth, and an anus forms separately. In deuterostomes this is reversed.

Outpocketings of the archenteron (primitive gut) of the gastrula which form the mesodermal somites later in development. The cavities within the pouches will form the body cavity. Found in animals such as Amphioxus and many echinoderms.

epithelial cells found at the initial site of gastrulation, lining the initial archenteron, that temporarily become bottle-shaped; they maintain contact with the outer surface of the embryo, but the majority of the cell is inside the embryo.

The opening into the gastrula is known as the blastopore. The inner cavity created by the infolding is known as the archenteron. [edit] Movements ...
