Cortical Reaction. Soon after the fusion of the plasma membranes, the oocyte shows cortical reactions. Sperm Entry. Karyogamy. Activation of Eggs.
What is the usual site of fertilization?
Fallopian tubes receive the ovum from the ovary and provide a site where fertilization of ovum can take place. The most common place for fertilization is the ampulla of fallopian tube. In addition, they also provide nourishment for the fertilized ovum and transport it to the cavity of the uterus.
