The target of FSH is the _____.
- A. prostate
- B. seminiferous tubule
- C. pituitary
- D. penis
Correct Answer: B
Rationale: The correct answer is B: seminiferous tubule. FSH (follicle-stimulating hormone) targets the seminiferous tubules in the testes to stimulate the production of sperm. FSH plays a crucial role in male reproductive function by promoting spermatogenesis. The other choices are incorrect because:
A: Prostate - FSH does not directly target the prostate.
C: Pituitary - FSH is secreted by the pituitary gland, it does not target the pituitary itself.
D: Penis - FSH does not have a direct role in the structure or function of the penis.

What area experiences the greatest changes in a menstrual cycle?
- A. vagina
- B. perimetrium
- C. cervix
- D. endometrium
Correct Answer: D
Rationale: The correct answer is D: endometrium. The endometrium undergoes the most significant changes during the menstrual cycle. It thickens and sheds in response to hormonal changes for potential implantation of a fertilized egg. The vagina (A), perimetrium (B), and cervix (C) do not experience the same level of cyclic changes as the endometrium. The vagina is primarily a passageway, the perimetrium is the outer layer of the uterus, and the cervix mainly functions as an opening to the uterus. Therefore, the endometrium is the area that experiences the greatest changes in a menstrual cycle due to its role in preparing for possible pregnancy and shedding if implantation does not occur.
There are ____________ facial bones
- A. 14
- B. 22
- C. 50
- D. 16
Correct Answer: B
Rationale: The correct answer is B: 22. There are a total of 22 facial bones in the human skull. These bones include the mandible, maxilla, zygomatic bone, nasal bone, and others. Understanding human anatomy is crucial for healthcare professionals. Choice A (14) is too low and does not accurately represent the number of facial bones. Choice C (50) is too high and exceeds the actual count of facial bones. Choice D (16) is also incorrect as it falls short of the correct count of 22. Knowing the exact number of facial bones is important for various medical fields such as surgery, dentistry, and radiology.
Which of the following does not occur during puberty in a female?
- A. Increased fat deposits beneath the skin
- B. Onset of menopause
- C. Widening and lightening of the pelvis
- D. Development of the breasts
Correct Answer: B
Rationale: The correct answer is B: Onset of menopause. Puberty is the period of sexual maturation and development, typically occurring in adolescence. Menopause, on the other hand, is the cessation of menstruation and fertility, usually happening in women in their late 40s or early 50s. During puberty in females, there is an increase in fat deposits beneath the skin, widening and lightening of the pelvis to prepare for childbirth, and development of the breasts as part of secondary sexual characteristics. Menopause does not occur during puberty; it is a separate phase in a woman's reproductive life cycle. Therefore, B is the correct answer.
What is the first stage of labour?
- A. Dilation of the cervix.
- B. Delivery of the infant.
- C. Contraction of the uterus.
- D. Delivery of the placent
Correct Answer: A
Rationale: The correct answer is A: Dilation of the cervix. This is the first stage of labor, where the cervix begins to open and thin out to allow the baby to pass through the birth canal. This process is crucial in preparing the body for delivery. The other choices are incorrect as they occur in later stages of labor. B: Delivery of the infant is the second stage, C: Contraction of the uterus is a general process throughout labor, and D: Delivery of the placenta is the third stage after the baby is born.
