In male embryos, which hormone is responsible for the development of the urethra, prostate, and external genitals?

  • A. dihydrotestosterone (DHT)
  • B. FSH
  • C. Progesterone
  • D. Estrogen
Correct Answer: A

Rationale: The correct answer is A: dihydrotestosterone (DHT). DHT is a potent form of testosterone responsible for male sexual development, including the formation of the urethra, prostate, and external genitals. It binds to androgen receptors in target tissues, promoting their growth and differentiation. FSH (Choice B) is follicle-stimulating hormone, which primarily regulates sperm production in males. Progesterone (Choice C) is a female sex hormone involved in the menstrual cycle and pregnancy. Estrogen (Choice D) is a female sex hormone responsible for female reproductive development. Thus, A is the correct answer as it specifically pertains to male sexual differentiation.

Which statement regarding the uterus is true:

  • A. it is pear-shaped;
  • B. the superior extremity is represented by the corpus;
  • C. the vagina is inserted on the inferior extremity;
  • D. it is located laterally in the pelvis;
Correct Answer: A

Rationale: The correct answer is A: it is pear-shaped. The uterus is indeed pear-shaped in structure, with a wider upper part called the corpus and a narrower lower part called the cervix. The pear shape allows for the expansion required during pregnancy. The other choices are incorrect: B is inaccurate as the superior extremity is the fundus, not the corpus; C is incorrect as the vagina is connected to the cervix, not the inferior extremity; D is wrong as the uterus is located centrally in the pelvis.

Which of the following is a form of sexual reproduction?

  • A. Fragmentation.
  • B. Parthenogenesis.
  • C. Budding.
  • D. Hermaphroditism
Correct Answer: D

Rationale: Step 1: Define sexual reproduction as the process involving the fusion of gametes from two parents.
Step 2: Hermaphroditism refers to an organism having both male and female reproductive organs for self-fertilization.
Step 3: In hermaphroditism, there is still a fusion of gametes, fulfilling the criteria of sexual reproduction.
Step 4: Fragmentation, parthenogenesis, and budding are forms of asexual reproduction, not involving the fusion of gametes.
Step 5: Therefore, the correct answer is D (Hermaphroditism) as it aligns with the definition and process of sexual reproduction.

Parturition is another term for

  • A. secretory phase ________.
  • B. placental stage
  • C. menopause
  • D. postpartum stage
Correct Answer: D

Rationale: Parturition refers to the process of giving birth. The postpartum stage immediately follows childbirth, involving recovery and adjustment to motherhood. The secretory phase is a phase of the menstrual cycle involving hormonal changes, not related to childbirth. The placental stage refers to the stage after the baby is born when the placenta is delivered. Menopause is the natural cessation of menstruation and fertility in women, occurring later in life and not related to childbirth. Therefore, the correct answer is D because it directly relates to the process of giving birth.
