Which part of the uterus opens into the vagina?
- A. Urethra
- B. Cervix
- C. Uterine tubes
- D. Inguinal canal
Correct Answer: B
Rationale: The correct answer is B: Cervix. The cervix is the lower part of the uterus that opens into the vagina. It acts as a barrier between the uterus and vagina, and allows for the passage of menstrual flow, sperm, and a baby during childbirth. The other choices are incorrect because the urethra is a tube that connects the bladder to the outside of the body, the uterine tubes are also known as fallopian tubes that connect the ovaries to the uterus, and the inguinal canal is a passage in the abdominal wall.

Mastoid process is part of which bone?
- A. Temporal
- B. Mandible
- C. Maxilla
- D. Ethmoid
Correct Answer: A
Rationale: The correct answer is A: Temporal. The mastoid process is a bony projection located on the temporal bone, which is situated behind the ear. It serves as an attachment site for various neck muscles. The temporal bone also houses important structures like the middle and inner ear components. The other choices, B: Mandible, C: Maxilla, and D: Ethmoid, are incorrect because the mastoid process is not located on these bones. The mandible is the jawbone, the maxilla forms the upper jaw, and the ethmoid bone is located in the skull's orbit and nasal cavity. Therefore, based on its anatomical location and function, the correct answer is A: Temporal.
What structure corresponds to the scrotum in the male?
- A. labia major
- B. labia minor
- C. pudendal cleft
- D. mons pubis
Correct Answer: A
Rationale: The correct answer is A: labia major. The scrotum in males corresponds to the labia major in females as they both serve as protective structures for the reproductive organs. The labia major in females is analogous to the scrotum in males in terms of function and location. The other choices are incorrect because the labia minor (B) is a smaller structure located inside the labia major, the pudendal cleft (C) refers to the space between the labia major and labia minor, and the mons pubis (D) is a rounded, fatty area located over the pubic bone.

Spermatogenesis (A) is the process of creating male gametes (sperm). Spermiogenesis (C) is the final stage of spermatogenesis where spermatids mature into sperm. Cleavage (D) refers to the rapid cell divisions that occur after fertilization. Therefore, B is the correct answer as it specifically relates to the formation of female gametes.
