   blastopore
   During gastrulation cells on the surface of the embryo move into the interior to form the mesoderm and endoderm. The opening formed by this invagination of cells is the blastopore. It is an opening from the archenteron, the primitive gut, to the exterior. In some animals this opening becomes the anus, whilst in others it closes up and the anus opens at the same spot or nearby. In some animals, eg. chick, invagination occurs without a true blastopore and the site at which the cells move in, the (primitive streak), may be termed a virtual blastopore.

   Blastopore
   A `blastopore` is an opening into the archenteron during the embryonic stages of an organism. The distinction between protostomes and deuterostomes is based on the direction in which the mouth (stoma) develops in relation to the blastopore. Protostome derives from the Greek word protostoma meaning `first mouth` whereas Deuterostome's etymology is `second mouth` from the words second and mouth . The major distinctions between deuterostomes and pr...
