How does the fertilized ovum become an embryo?

Answer 1

It will begin to divide and divide becoming an embryo. It begins with one cell and continues until it is millions of cells and these will be seen:scalp vascular plexus, eyelid, eye, nose, auricle of external ear, mouth, shoulder, arm, elbow, wrist, toes separated, sole of foot and umbilical cord.

It is called an embryo until about eight weeks after fertilization. After this development is considered fetal for the remainder of the pregnancy.

Answer 3

After fertilization, the zygote undergoes multiple cell divisions to form a ball of cells called a morula. The morula then transforms into a blastocyst, in which two distinct cell types are present: the inner cell mass and the outer cell layer. The inner cell mass develops into the embryo, while the outer cell layer becomes the placenta and other supporting structures.
