Embryonic Development and Implantation

Embryonic development refers to the series of events that occur after fertilization leading to the formation of a multicellular embryo. Following fertilization, the zygote undergoes multiple rounds of mitotic cell divisions to generate a solid ball of cells known as the morula. The morula then undergoes compaction and forms a hollow sphere called the blastocyst, consisting of an inner cell mass and an outer layer of trophoblast cells. The inner cell mass will give rise to the embryo, while the t...
