De*lam`i*na"tion, n. (Biol.)
Definition: Formation and separation of laminæ or layers; one of the
methods by which the various blastodermic layers of the ovum are
differentiated.
Note: This process consists of a concentric splitting of the cells of
the blastosphere into an outer layer (epiblast) and an inner layer
(hypoblast). By the perforation of the resultant two-walled vesicle,
a gastrula results similar to that formed by the process of
invagination.
