Question

The part of the fallopian tube closest to ovary
A. Ampulla
B. Isthmus
C. Infundibulum
D. Cervix

Answer 1

Hint: An egg is transported from the ovary to the uterus by the uterine tube (fallopian tube). Women should have two uterine tubes in their bodies unless a biological abnormality, surgery, or ectopic pregnancy has caused the loss of one tube.

Complete Answer:
- Generally, a part of the fallopian tubes, called the ampulla, is where an egg is fertilised by the sperm of a man. The resulting fertilised egg then travels to the uterus where it continues to grow until birth. Some women may have a tubal or ectopic pregnancy that puts their fallopian tube and their lives at risk.
- Instead of moving to the uterus, ectopic pregnancies result from a fertilised egg lingering in the tube. They are treated with surgery that ends the pregnancy process.
- Four sections are made of the Fallopian tube. These are the infundibulum with its associated fimbriae near the ovary, the ampulla representing the main part of the lateral tube, the isthmus, the narrower part of the tube that connects to the uterus, and the interstitial (or intramural) part, the narrowest part of the uterine tube that crosses the muscles of the uterus, defined from near the ovaries to inwards near the uterus. A Fallopian tube has an average length of 11-12 cm.
- The fallopian tube helps an egg to travel from the ovary to the uterus. It is surrounded by a spherical array of cells known as an ovarian follicle while an oocyte is growing in an ovary.
- Just before ovulation, to establish the first polar body and a secondary oocyte that is arrested in the meiosis II metaphase, the primary oocyte completes meiosis I. The uterus is an inverted pear-shaped muscular organ with a thick wall that has three parts. A cervix is the narrow end of the uterus that projects into the vagina.

Hence, the correct answer is option (A) Ampulla.

Note: The fertility of a woman may be impaired by defects or damage to the fallopian tubes. For example, if the tubes are blocked or destroyed, sperm can not enter the egg or the fertilised egg can be prevented from moving to the uterus. There are different causes of anomalies in the structure and function of the fallopian tube, including pelvic infection (e.g. pelvic inflammatory disease), endometriosis, and congenital defects.
