Middle layer of uterus is called:
- A. Endometrium
- B. Ectometrium
- C. Myometrium
- D. Perimetrium.
Correct Answer: C
Rationale: The correct answer is C: Myometrium. The myometrium is the middle layer of the uterus composed of smooth muscle tissue responsible for uterine contractions during childbirth. The endometrium (A) is the innermost layer responsible for menstruation and implantation. Ectometrium (B) is not a correct term. Perimetrium (D) is the outermost layer of the uterus. Therefore, C is the correct choice as it accurately represents the middle layer of the uterus.

The female Bartholin glands correspond to the male _____.
- A. prostate
- B. Cowper's
- C. seminal vesicle
- D. glans
Correct Answer: B
Rationale: The female Bartholin glands are homologous to the male Cowper's glands. Both glands secrete fluid to lubricate the reproductive tract during sexual arousal. The prostate gland (choice A) is not the correct answer as it is a different structure that produces seminal fluid. The seminal vesicles (choice C) secrete a significant portion of the seminal fluid but are not the male counterpart to the Bartholin glands. The glans (choice D) refers to the tip of the penis and is not the correct counterpart to the Bartholin glands. Therefore, the correct answer is B, Cowper's glands.
Which of the following is a surgical procedure in which a pendulous breast is lifted and fixed to the chest wall?
- A. Mastostomy
- B. Mastectomy
- C. Mastopexy
- D. Mesopexy
Correct Answer: C
Rationale: The correct answer is C: Mastopexy. This surgical procedure involves lifting and fixing a pendulous breast to the chest wall to achieve a more youthful and firmer appearance. It does not involve removal of breast tissue like in mastectomy (B) or creation of a new breast mound like in mastostomy (A). Mesopexy (D) is not a recognized surgical procedure for breast lifting.
_____________________ is a vascular organ that is formed within the uterine wall
- A. Amnion
- B. Chorion
- C. Placenta
- D. Endometrium
Correct Answer: C
Rationale: The correct answer is C: Placenta. The placenta is a vascular organ that develops within the uterine wall during pregnancy. It serves as a connection between the mother and fetus for nutrient and waste exchange. The amnion (A) and chorion (B) are fetal membranes, not vascular organs, and the endometrium (D) is the inner lining of the uterus where the placenta attaches.
Which term includes the other terms?
- A. spermatozoa
- B. alkaline mucus
- C. semen
- D. fructose
Correct Answer: C
Rationale: The correct answer is C: semen. Semen is the fluid that contains spermatozoa, alkaline mucus, and fructose. Spermatozoa are the male reproductive cells, alkaline mucus helps neutralize vaginal acidity, and fructose provides energy for sperm. Semen is the combination of these components, making it the term that encompasses all the other terms listed. A: spermatozoa is incorrect because it is just one component of semen. B: alkaline mucus is incorrect as it is a separate component in semen. D: fructose is incorrect because it is also just one component found in semen.
During fetal development which cells give rise to primary oocytes?
- A. Spermatogonia
- B. Secondary oocytes
- C. Oogonia
- D. Granulosa cells
Correct Answer: C
Rationale: The correct answer is C: Oogonia. Oogonia are the cells that give rise to primary oocytes during fetal development. Oogonia undergo mitosis to produce primary oocytes, which then enter meiosis I to form secondary oocytes. Spermatogonia (A) are male germ cells that develop into sperm, not oocytes. Secondary oocytes (B) are formed from primary oocytes in the ovary after meiosis I completion. Granulosa cells (D) are somatic cells in the ovary that support oocyte development but do not give rise to oocytes themselves.
