PATHOLOGY

Detailed explanation-1: -zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Detailed explanation-2: -A developing, fertilized egg is known by several names within the first 2 weeks after conception, including zygote, morula (day 4), and blastocyst (day 5).

Detailed explanation-3: -Fertilization takes place in the fallopian tube. The fertilized egg is called the zygote.

Detailed explanation-4: -A pregnancy starts with fertilization, when a woman’s egg joins with a man’s sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
