Advanced Seminal Vesicle Quiz

Q1. From which embryologic structure do the seminal vesicles develop?

• Neural tube
• Paramesonephric ducts
• Mesonephric ducts
• Allantois only

Q2. What type of mucosal architecture characterizes the seminal vesicles?

• Keratinized epidermis
• Highly folded mucosa
• Cartilage lined cavities
• Flat mucosa without folds

Q3. What epithelial type commonly lines the seminal vesicles?

• Transitional epithelium throughout
• Keratinized stratified squamous epithelium
• Pseudostratified columnar epithelium
• Simple squamous epithelium only

Q4. Why do seminal vesicles appear sacculated externally?

• Division by skeletal muscle septa
• Calcification of the wall
• Presence of multiple separate glands
• Extensive coiling and folding of the glandular tube

Q5. Why can obstruction of an ejaculatory duct affect seminal vesicle drainage?

• Its secretion enters the bloodstream only
• It empties directly into the urinary bladder
• The seminal vesicle empties through the ejaculatory duct pathway
• The seminal vesicle drains through the ureter

Q6. What is the functional significance of smooth muscle in the seminal vesicle wall?

• It produces sperm by meiosis
• It propels seminal vesicle secretion during emission
• It filters blood
• It forms the external urethral sphincter

Q7. Why are seminal vesicles not simply storage sacs for sperm?

• They are secretory glands rather than primary sperm storage organs
• They lack any ductal connection
• They are lymphatic organs
• They produce urine rather than reproductive fluid

Q8. Which anatomical relationship is important during examination or surgery involving the rectum and prostate?

• They lie between the bladder and rectum near the prostate
• They surround the abdominal aorta
• They lie within the scrotal skin
• They are located in the inguinal canal

Q9. How does sympathetic activation contribute to emission?

• It produces sperm in the urethra
• It promotes coordinated smooth muscle contraction of reproductive ducts and glands
• It opens the ureters into the prostate
• It stops all glandular secretion

Q10. Which statement best integrates seminal vesicle anatomy and function?

• Paired gonads that produce sperm and testosterone
• Paired coiled glands behind the bladder that secrete seminal fluid into the ejaculatory pathway
• Superficial perineal lymph nodes
• Muscular sphincters at the bladder neck
