**SECTION ONE**
, 1. Which of the following structures is the primary site of spermatogenesis in the male
reproductive system?
A. Epididymis
B. Vas deferens
C. Seminiferous tubules
D. Seminal vesicles
🟢 C. Seminiferous tubules
🔴 Explanation: Spermatogenesis occurs within the seminiferous tubules of the testes,
where germ cells mature into spermatozoa through meiosis and spermiogenesis.
2. During the ovarian cycle, a surge in which hormone is directly responsible for
triggering ovulation?
A. Follicle-stimulating hormone (FSH)
B. Luteinizing hormone (LH)
C. Estrogen
D. Progesterone
🟢 B. Luteinizing hormone (LH)
,🔴 Explanation: A sharp increase or "surge" in LH levels around day 14 of the cycle
weakens the follicular wall and stimulates the release of the secondary oocyte.
3. Which layer of the uterine wall is shed during menstruation?
A. Myometrium
B. Perimetrium
C. Stratum basalis
D. Stratum functionalis
🟢 D. Stratum functionalis
🔴 Explanation: The stratum functionalis is the superficial layer of the endometrium that
undergoes cyclic changes in response to hormones and is sloughed off during menses.
4. A patient is diagnosed with an ectopic pregnancy. Where does this condition most
commonly occur?
A. Ovary
B. Fallopian tube
C. Cervix
D. Abdominal cavity
🟢 B. Fallopian tube
, 🔴 Explanation: Most ectopic pregnancies occur in the fallopian (uterine) tube,
specifically in the ampulla, when the fertilized egg fails to reach the uterus.
5. What is the function of the interstitial (Leydig) cells in the testes?
A. Production of inhibin
B. Nourishment of developing sperm
C. Production of testosterone
D. Formation of the blood-testis barrier
🟢 C. Production of testosterone
🔴 Explanation: Interstitial cells located between the seminiferous tubules secrete
testosterone in response to stimulation by luteinizing hormone.
6. Which of the following is the correct sequence of sperm travel through the male
duct system?
A. Seminiferous tubules, rete testis, epididymis, ductus deferens, urethra
B. Rete testis, seminiferous tubules, ductus deferens, epididymis, urethra
C. Epididymis, rete testis, seminiferous tubules, urethra, ductus deferens
D. Seminiferous tubules, epididymis, rete testis, ductus deferens, urethra
🟢 A. Seminiferous tubules, rete testis, epididymis, ductus deferens, urethra
