1. Which of the following are layers of endometrium in pregnancy EXCEPT?

• A. Decidua compacta
• B. Decidua spongiosum
• C. Decidua functionalis
• D. Decidua basalis

Correct answer: C

Rationale: During pregnancy, the layers of endometrium include decidua compacta, decidua spongiosum, and decidua basalis. Decidua functionalis is the layer that sheds during menstruation and regenerates each cycle, not a layer of the endometrium during pregnancy. Therefore, choice C is the correct answer. Decidua compacta is the layer closest to the conceptus, decidua spongiosum is the middle layer, and decidua basalis is the layer adjacent to the myometrium.

2. Causes of metrorrhagia include:

• A. Cervical carcinoma
• B. Uterine polyp
• C. Cervical endometriosis
• D. Infections like Chlamydia

Correct answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

3. Outlet of the true pelvis anteriorly bounded by:

• A. Ischiopubic arch (T)
• B. Linea terminalis (F)
• C. Coccyx (T)
• D. Promontory of the sacrum (F)

Correct answer: A

Rationale: The correct answer is A: Ischiopubic arch. The outlet of the true pelvis is indeed anteriorly bounded by the ischiopubic arch, which consists of the ischium and the pubic bones. This structure forms the lower boundary of the pelvic outlet. The other choices, B, C, and D, are incorrect. The linea terminalis (pelvic brim) forms the upper boundary of the true pelvis, the coccyx is part of the bony pelvis but does not bound the pelvic outlet anteriorly, and the promontory of the sacrum is located in the posterior part of the pelvis, not the anterior boundary of the pelvic outlet.

4. What type of tissue lines the testes?

• A. Glandular tissue.
• B. Squamous epithelium.
• C. Transitional epithelium.
• D. Stratified epithelium.

Correct answer: A

Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.

5. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:

• A. Ovulation
• B. Regenerative
• C. Secretory
• D. Menstruation

Correct answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.
