tent of invagination as indicated by the length of the archenteron. In early
gastrulae invagination is just beginning and the archenteron is short. In late
gastrulae, which have become elongated, the archenteron extends over half the
length of the ...
Richard Marshall Eakin, 1978
By fixation to the inner surface of the blastoderm, they form a ring at the base of
the invaginating archenteron. The filopodia of the primary mesenchyme cells in
the ring fuse with one another to form a syncytial cable-like structure.

Eventually the anterior end of the archenteron acquires an opening to the exterior
, which becomes the mouth. Perhaps surprisingly, the anus is not formed from the
blastopore: the latter closes up and a new connection with the exterior, formed ...

length of the blastocoel and then arrests temporarily. After a short pause,
secondary invagination begins. The archenteron elongates considerably (two to
threefold) during secondary invagination, until it reaches the blastocoel roof (Fig.
10D).

A sagittal view shows that the archenteron has deepened and expanded
tremendously Fig. 61, (A), and the blastocoel is decreased in size and crowded
over to the anteroventral side (Fig. 61, BL). The yolk plug (Fig. 61, YP) obscures
the ...

Archenteron Invagination As the ring of primary mesenchymal cells forms in the
vegetal region of the blastocoel, important changes are occuring in the cells that
remain at the vegetal plate. These cells remain bound to one another and to the ...

The end of the archenteron then swells and pinches off mesoderrn to left and
right in the form of two vasoperitoneal vesicles (Fig.6, a to c), i.e. two coelomic
sacs enveloped by mesoderm. These coelomic sacs divide rapidly into three
sections, ...

It is known that in the dorsal mesendoderm the differentiation tendencies of both

of invagination. When isolated before its invagination and enveloped in ...
