Arthropod Relationships
Protostomes typically show a blastopore which becomes divided into mouth and
anus by fusion of the lateral blastopore lips. Their central nervous system (Figure

Life (Loose Leaf): The Science of Biology
Gastrulation begins when cells just below the center of the gray crescent move
inward to form the dorsal lip of the future blastopore. Cells of the animal pole
spread out, pushing surface cells below them toward and across the dorsal lip.

Pregastrulation — In the late blastula, shortly before the appearance of the
blastopore, certain pregastrulatory activities have been observed. Thus,
pregastrulation includes three processes — displacement of the marginal zone,
contraction of ...

Cells at the dorsal lip of the blastopore change shape and sink below the surface
as they move to the interior. These cells are replaced by cells that move from their
original positions on the surface of the embryo to the dorsal lip. As a result, the ...
