Advanced Prostate Gland Quiz

Q1. Why can benign prostatic hyperplasia cause urinary obstruction?

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

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

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

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

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

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

• Somatic fibers from the radial nerve
• Phrenic nerve fibers only
• 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 the optic nerves
• They carry urine from the bladder
• They contain autonomic fibers important for erectile function

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

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

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

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

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

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

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

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

Q10. Which statement best integrates prostate anatomy and function?

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