Introduction
(Latin, morula = mulberry) An early stage in post-fertilization development when cells have rapidly divided to produce a solid mass of cells (12-15 cells) with a "mulberry" appearance. This stage is followed by formation of a cavity in this cellular mass blastocyst stage. In humans, morula stage of development occurs during the first days of the first week following fertilization. This developmental stage is followed by formation of the blastocyst.
