A young woman is given daily injections of a substance beginning on the 16th day of her normal menstrual cycle and continuing for 3 weeks. As long as the injections continue, she does not menstruate. The injected substance could be which of the following?
- A. Testosterone
- B. FSH
- C. An inhibitor of progesterone’s actions
- D. A prostaglandin E2 inhibitor
Correct Answer: C
Rationale: The correct answer is C: An inhibitor of progesterone’s actions. Progesterone is responsible for maintaining the uterine lining, and inhibiting its actions would prevent menstruation. Testosterone (A) and FSH (B) do not directly affect menstruation. Prostaglandin E2 (D) is involved in the menstrual process, but inhibiting it would not necessarily stop menstruation.

Which of the following are all components of sperm?
- A. acrosome, flagellum, nucleus
- B. codpiece, flagellum, midpiece
- C. nucleus, seminal vesicles, mitochondria
- D. DNA, flagellum, efferent ductules
Correct Answer: A
Rationale: The correct answer is A: acrosome, flagellum, nucleus. The acrosome contains enzymes for penetrating the egg. The flagellum is the tail for movement. The nucleus contains genetic material. Choice B is incorrect because a codpiece is a protective garment and not a component of sperm. Choice C is incorrect because seminal vesicles and mitochondria are not components of sperm. Choice D is incorrect because efferent ductules are part of the male reproductive system, not a component of sperm.

- A. Irregular bone
- B. Short bone
- C. Sesamoid bone
- D. Flat bone
Correct Answer: C
Rationale: The patella is a sesamoid bone located within the tendon of the quadriceps femoris muscle.

Process of giving birth is termed as
- A. Lactation
- B. Gestation
- C. Micturition
- D. parturition
Correct Answer: D
Rationale: The correct answer is D: parturition. Parturition refers to the process of giving birth. It involves the series of events that lead to the expulsion of the fetus from the mother's womb. Lactation (choice A) is the production of milk by the mammary glands after birth. Gestation (choice B) is the period of development of the fetus in the womb. Micturition (choice C) is the process of urination and is not related to childbirth. Therefore, the term that specifically describes the process of giving birth is parturition.
The failure of a testes to descend is referred to as _____.
- A. inguinal hernia
- B. strangulated hernia
- C. vaginal process
- D. cryptorchidism
Correct Answer: D
Rationale: The correct answer is D: cryptorchidism. This is because cryptorchidism specifically refers to the failure of one or both testes to descend into the scrotum. It is a common condition in newborns and can lead to complications if not treated.
A: Inguinal hernia is the protrusion of abdominal contents through the inguinal canal, not related to testes descent.
B: Strangulated hernia occurs when the blood supply to the herniated tissue is cut off, not related to testes descent.
C: Vaginal process is a structure involved in testicular descent but does not describe the failure of testes descent itself.
Summary:
Cryptorchidism is the correct term for undescended testes, while the other options are unrelated conditions.
