Advanced Seminal Vesicle Quiz

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

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

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

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

Q3. What epithelial type commonly lines the seminal vesicles?

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

Q4. Why do seminal vesicles appear sacculated externally?

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

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

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

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

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

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

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

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 are located in the inguinal canal
• They lie within the scrotal skin
• They surround the abdominal aorta

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 stops all glandular secretion
• It opens the ureters into the prostate

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
• Muscular sphincters at the bladder neck
• Superficial perineal lymph nodes
