Advanced Bulbourethral Glands Quiz

Q1. Which embryologic tissue gives rise to the bulbourethral glands?

• Urogenital sinus epithelium
• Pharyngeal endoderm
• Paraxial mesoderm
• Neural tube

Q2. Which female glands are considered homologous to the bulbourethral glands?

• Ovaries
• Greater vestibular glands
• Mammary glands
• Paraurethral glands

Q3. Why are the long ducts of the bulbourethral glands anatomically important?

• They form the ejaculatory ducts
• They carry sperm from the testes
• They connect the kidneys to the bladder
• They connect deep perineal glands with the proximal spongy urethra

Q4. How does the location of the bulbourethral glands differ from that of the prostate?

• They lie inferior to the prostate in the deep perineal region
• They lie inside the scrotal skin
• They lie superior to the bladder
• They are embedded inside the prostate

Q5. Why can obstruction of a bulbourethral duct cause a retention cyst or duct dilation?

• Blocked drainage can cause secretions to accumulate
• Obstruction increases urine production
• The gland becomes part of the ureter
• The duct normally drains lymph

Q6. Which lymphatic pathway is most consistent with the deep perineal location of the bulbourethral glands?

• Popliteal lymph nodes
• Axillary lymph nodes
• Internal iliac lymph nodes
• Submental lymph nodes

Q7. Why is bulbourethral mucus useful before ejaculation?

• It closes the urethra to semen
• It lubricates and conditions the urethral passage
• It contracts the urinary bladder
• It produces sperm chromosomes

Q8. Which feature distinguishes bulbourethral glands from the testes?

• They produce sperm within seminiferous tubules
• They are enclosed by tunica albuginea as gonads
• They are accessory mucus secreting glands rather than gonads
• They drain primarily through efferent ductules

Q9. What anatomical relationship places the glands at risk during procedures involving the deep perineal urethra?

• They are attached to the epididymal tail
• They lie within the renal hilum
• They lie close to the membranous urethra and external urethral sphincter
• They surround the abdominal aorta

Q10. Which statement best integrates bulbourethral gland anatomy and function?

• Paired deep perineal glands that secrete mucus into the proximal spongy urethra
• Paired gonads that produce sperm and testosterone
• Muscular sphincters surrounding the bladder neck
• Superficial groin nodes draining the scrotum
