UNFERTILIZED EGG
UNFERTILIZED EGG The embryonic disc of a sterile egg bears an accumulation of white material at its center GURRAM SRINIVAS
FERTILIZED EGG
FERTILIZED EGG The fertilized embryonic disc looks like a ring: It has a central area, lighter in color – house the embryo. GURRAM SRINIVAS
The germinal disc is at the blastodermal stage.
The germinal disc is at the blastodermal stage. The segmentation cavity, under the area pellucida, takes on the shape of a dark ring. GURRAM SRINIVAS

Appearance of the first groove at the center of the blastoderm.
Appearance of the first groove at the center of the blastoderm. Among extraembryonic annexes, appearance of the vitelline membrane –plays a major role in embryo nutrition. GURRAM SRINIVAS
The embryo is lying on its left side.
The embryo is lying on its left side. Onset of blood circulation. The vitelline membrane spreads over the yolk surface. The head and trunk can be discerned, as well as the brain. Appearance of the cardiac structures which begin to beat. GURRAM SRINIVAS
