This set of Biology Multiple Choice Questions & Answers (MCQs) focuses on “The Female Reproductive System”.
1. The primary sex organ of female reproductive system is ______
a) fallopian tubes
Explanation: Ovaries are the primary female sex organs that produce the female gamete (ovum) and several steroid hormones (ovarian hormones). Each ovary is almond shaped, solid, greyish-pink in color.
2. The ovaries are suspended by _______
a) fallopian tubes
b) ovarian walls
Explanation: The ovaries are located one on each side of the lower abdomen, near the kidney of its side. It is suspended from the dorsal body wall by a mesentery, called mesovarium.
3. Outermost layer of ovary is made up of ________
a) simple cuboidal cells
Explanation: Ovarian or germinal epithelium is the outermost layer of ovary formed of simple cuboidal cells. It is actually modified visceral peritoneum.
4. Stroma consists of an outer ovarian ________ and inner ovarian ________
a) medulla, cortex
b) cortex, medulla
c) tunica albuginea, stroma
d) stroma, stroma
Explanation: Each ovary is a solid structure consisting of ovarian epithelium, tunica albuginea, ovarian cortex and stroma. Stroma consists of an outer ovarian cortex and inner ovarian medulla.
5. The ovarian ______ has a white body or corpus albicans.
Explanation: The ovarian cortex has a white body or corpus albicans. It represents the degenerating corpus luteum. Corpus Luteum secretes the hormone. Progesterone during pregnancy, and the hormone relaxin towards the end of pregnancy.
6. Ovarian Medulla contains many rounded or oval bodies, called _______
a) corpus luteum
b) ovarian follicles
c) corpus albicans
Explanation: Ovarian Medulla contains many rounded or oval bodies, called ovarian follicles in various stages of development. Each follicle contains a large ovum surrounded by many layers of follicle cells. The follicle cells of a maturing follicle secret oestrogens into the blood.
7. Fallopian tubes are also called as _______
Explanation: Fallopian tubes are also called as oviducts. Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus the part closer to the ovary is the funnel-shaped infundibulum.
8. The opening of the infundibulum into the body cavity is called ______
Explanation: The opening of the infundibulum into the body cavity is called ostium. The edges of the infundibulum possess motile, finger-like projections called fimbriae, which help in collection of the ovum after ovulation.
9. The last part of oviduct is called _________
Explanation: The infundibulum leads to a long, wider, thin walled part of the oviduct called ampulla. The last part of the oviduct, isthmus has a narrow lumen, short and thick walled and it joins the uterus.
10. Fertilization occurs in the oviduct.
Explanation: Fertilization of the ovum takes place in the upper portion of the fallopian tube. The fallopian tubes convey the ovum from the ovary to the uterus.
