Advanced Prostate Gland Quiz

Q1. Why can benign prostatic hyperplasia cause urinary obstruction?

• It prevents urine production by the nephrons
• It blocks both ureters inside the kidneys
• Transition zone enlargement can compress the prostatic urethra
• It closes the external urethral orifice directly

Q2. Why is the peripheral zone clinically important in prostate cancer?

• It is located entirely inside the bladder
• It contains no glandular tissue
• It is a common site of carcinoma and is accessible posteriorly
• It forms the external urethral sphincter

Q3. What is the anatomical significance of the prostatic venous plexus communicating with vertebral veins?

• It carries urine to the kidneys
• It provides a potential route for spread to the vertebral column
• It drains directly into superficial inguinal nodes
• It transports sperm into the epididymis

Q4. Which autonomic fibers are important for prostatic smooth muscle and secretory function?

• Phrenic nerve fibers only
• Somatic fibers from the radial nerve
• Optic nerve fibers
• Fibers from the inferior hypogastric and prostatic plexuses

Q5. Why are the neurovascular bundles near the posterolateral prostate clinically important?

• They form the spermatic cord
• They contain autonomic fibers important for erectile function
• They carry urine from the bladder
• They contain the optic nerves

Q6. What is the relationship between the ejaculatory ducts and the central zone?

• They enter the corpus spongiosum directly
• They pass through the transition zone into the bladder
• They remain outside the prostate
• The ejaculatory ducts pass through the central zone region

Q7. Which embryologic tissue gives rise to the glandular epithelium of the prostate?

• Endoderm of the urogenital sinus
• Surface ectoderm of the scrotum
• Paraxial mesoderm
• Neural crest

Q8. How does prostatic stroma differ from its glandular component?

• Stroma contains smooth muscle and connective tissue around glandular elements
• Glands are composed of skeletal muscle
• Stroma consists only of neurons
• Both are made entirely of cartilage

Q9. Why can enlargement of the median periurethral region affect the bladder outlet?

• It blocks the renal arteries
• It closes the ureters at the kidneys
• It prevents seminal vesicles from forming
• Enlargement near the bladder neck can obstruct urinary outflow

Q10. Which statement best integrates prostate anatomy and function?

• A glandular and fibromuscular organ surrounding the proximal urethra and contributing to semen
• A paired gonad producing sperm
• A lymph node draining the scrotal skin
• A superficial perineal muscle
