Module 9 Exam Review / Questions and Answers
Section 1: Male Reproductive Anatomy & Physiology

1. Which of the following structures is the site of spermatogenesis (sperm production)?

 A) Epididymis

 B) <mark>Seminiferous tubules</mark>

 C) Vas deferens

 D) Seminal vesicles

 E) Prostate gland

<mark>Correct Answer: B) Seminiferous tubules</mark>
Rationale: The seminiferous tubules are the coiled structures within the testes where
spermatogenesis occurs. They contain spermatogonia (stem cells) that develop into mature
spermatozoa through meiosis. The epididymis is for sperm maturation and storage, the vas
deferens for transport, and the accessory glands (seminal vesicles, prostate) produce seminal
fluid.

2. Which structure carries sperm from the epididymis to the ejaculatory duct?

 A) <mark>Vas deferens (ductus deferens)</mark>

 B) Efferent ductules

 C) Urethra

 D) Seminiferous tubules

 E) Rete testis

<mark>Correct Answer: A) Vas deferens (ductus deferens)</mark>
Rationale: The vas deferens is a muscular tube that transports mature sperm from the
epididymis upward through the spermatic cord, over the bladder, and down to join the
ejaculatory duct. Efferent ductules carry sperm from testes to epididymis, and the urethra is the
final passageway.

3. What is the correct pathway of sperm from production to ejaculation?

, ESTUDYR


 A) Seminiferous tubules → Epididymis → Vas deferens → Ejaculatory duct → Urethra

 B) Seminiferous tubules → Vas deferens → Epididymis → Ejaculatory duct → Urethra

 C) Epididymis → Seminiferous tubules → Vas deferens → Urethra → Ejaculatory duct

 D) Seminiferous tubules → Ejaculatory duct → Epididymis → Vas deferens → Urethra

 E) Vas deferens → Seminiferous tubules → Epididymis → Ejaculatory duct → Urethra

<mark>Correct Answer: A) Seminiferous tubules → Epididymis → Vas deferens → Ejaculatory
duct → Urethra</mark>
Rationale: This is the correct anatomical sequence: Production in seminiferous tubules →
maturation and storage in epididymis → transport via vas deferens → mixing with seminal fluid
at ejaculatory duct → expulsion through urethra.

4. Which of the following does NOT belong with the others as an accessory reproductive
gland?

 A) Seminal vesicles

 B) Prostate gland

 C) Bulbourethral glands

 D) <mark>Seminiferous tubules</mark>

 E) All are accessory glands

<mark>Correct Answer: D) Seminiferous tubules</mark>
Rationale: The seminiferous tubules are part of the testes and are the site of sperm production,
not an accessory gland. Accessory glands include the seminal vesicles, prostate gland, and
bulbourethral glands, which all contribute secretions to semen.

5. Which statement about the spongy urethra is CORRECT?

 A) It is the shortest portion of the male urethra

 B) It passes through the prostate gland

 C) <mark>It runs through the penis and opens at the external urethral orifice</mark>

 D) It receives secretions from the seminal vesicles

 E) It is surrounded by the prostate gland
