(b) Explain the events during fertilization of an ovum in humans.

Answer 1

Parts of uterus and fallopian tube are marked below.

Explanation:

• Female reproductive system consists of a few organs - ovary, fallopian tube, uterus, cervix, and vaginal tube.

• The fallopian tube has three parts - fimbrae of the infundibulum, the ampulla, and the isthmus.

• The uterus is a trilayered structure - perimetrium, myometrium and endometrium from outside inward.

• The fertilization is the event of fusion between the male gamete sperm and the female gamete ovum.

• The fertilization begins with the entry of sperm by piercing the ovule walls by acrosomal enzymes.

• This results in the entry of sperm nucleus inside the ovum.

• Then the two nucleus fuse with each other and the chromosomes arrange themselves in the metaphasal plane and the 1st cleavage division takes place.
