Color Atlas of Embryology
Blastula. The cells of the morula form a hollow sphere, the blastula. The cavity of
the blastula is the blastocoel. The blastula possesses an animal and a vegetal
pole. The animal pole of the sea urchin blastula is characterized by a tuft of cilia.
The blastula stage normally is reached as the embryo enters the uterus. The
endoderm is responsible for the gill arches found in the early embryonic states of
vertebrates. In fish, these develop into respiratory organs. In land vertebrates,
they ...

Pattern Formation in Zebrafish
2 Mid-Blastula Transition and the Beginning of Cell Motility The earliest cell
rearrangements in the zebrafish blastula are the simple result of cell divisions. In
the cleavage-stage embryo, cells divide synchronously and rapidly, every 15min.
