Blastocyst Development Embryology

(Greek, blastos = sprout + cystos = cavity) or blastula, the term used to describe the hollow cellular mass that forms in early development. The blastocyst consists of cells forming an outer trophectoderm (TE, trophoblast) layer, an inner cell mass (ICM, embryo blast) and a blastocoel (fluidfilled cavity). The inner cell mass will form the entire embryo, and is the source of true embryonic
