1. The endometrial tissue of the cervix is arranged in folds known as:

• A. Racemose glands
• B. Rugae
• C. Arbor vitae
• D. Peritoneum

Correct answer: B

Rationale: The endometrial tissue of the cervix is arranged in folds known as rugae, not Arbor vitae. Rugae are commonly found in anatomical structures like the stomach and bladder to allow expansion. Choices A, C, and D are incorrect. Racemose glands refer to branched compound glands, Arbor vitae is the tree-like appearance of the cerebellum, and Peritoneum is the serous membrane lining the abdominal cavity.

2. 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.

3. At 34-40 weeks of pregnancy, the breast changes include:

• A. Nipples become prominent and mobile.
• B. Colostrum can be expressed.
• C. Breasts become tender.
• D. Montgomery's tubercles are prominent.

Correct answer: D

Rationale: During the 34-40 weeks of pregnancy, Montgomery's tubercles become prominent. These are sebaceous glands on the areola, not the nipples. Choice A is incorrect as it describes the changes in nipples, not Montgomery's tubercles. Choice B is incorrect as colostrum production usually starts around the 16th week. Choice C is incorrect as breast tenderness is more common in early pregnancy due to hormonal changes.

4. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

5. Each breast is situated on each side of the sternum and extends between the:

• A. 1st and 6th rib
• B. 2nd and 6th rib
• C. 3rd and 6th rib
• D. 4th and 6th rib

Correct answer: B

Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.
