Question

Fertilisation occurs in which part of the fallopian tube?

• A. Ampulla
• B. Infundibulum
• C. Fimbriae
• D. Uterine part

Answer 1

The correct option is A Ampulla

After the release of sperm into the female reproductive tract, these sperms being motile swim through the vagina to the cervix to the uterus and further up to the fallopian tube. The fallopian tube is made of three regions, they are the infundibulum, ampulla and isthmus. The infundibulum is the funnel-shaped part of the fallopian tube that possess finger-like projections called fimbriae at its edges. Ampulla is the wider part of the fallopian tube after the infundibulum. The isthmus is a narrow region of the fallopian tube that joins the uterus. Sperm travels from isthmus to ampulla. Egg is collected by the fimbriae of the infundibulum. Egg is pushed by ciliated columnar epithelial cells to the ampullary region. Fertilisation takes place in the ampullary region of the fallopian tube.
