Definitions:

Late Blastula

A stage in embryonic development characterized by a spherical layer of cells (the blastoderm) surrounding a fluid-filled cavity (the blastocoel).

Morula

A solid ball of cells resulting from division of a fertilized ovum, and from which a blastula is formed.

Primitive Streak

Dynamic, constantly changing structure that forms at the midline of the blastodisc in birds, mammals, and some other vertebrates. It is active in gastrulation as cells migrate to a narrow furrow at its center, the primitive groove, and sink into the interior of the embryo. The anterior end of the primitive streak is Hensen’s node.

Epiblast

An early embryo layer from which all the three primary germ layers develop during gastrulation in the formation of a vertebrate body.
