Intermediate Glans Penis Quiz

Q1. How is the glans related to the corpora cavernosa?

• It lies inside the prostate
• It caps the distal ends of the corpora cavernosa
• It forms the proximal crura of the corpora cavernosa
• It forms the scrotal septum

Q2. Which part of the urethra traverses the glans penis?

• Intramural urethra
• Terminal spongy urethra
• Prostatic urethra
• Membranous urethra only

Q3. What is the fossa navicularis?

• A dilation of the spongy urethra within the glans
• A space inside the corpus cavernosum
• A recess within the urinary bladder
• A cavity in the prostate

Q4. Which nerve provides major somatic sensory innervation to the glans penis?

• Femoral nerve
• Dorsal nerve of the penis
• Obturator nerve
• Phrenic nerve

Q5. The dorsal nerve of the penis is a branch of which nerve?

• Femoral nerve
• Obturator nerve
• Vagus nerve
• Pudendal nerve

Q6. Which arteries are major contributors to the arterial supply of the glans?

• Posterior cerebral arteries
• Superior mesenteric arteries
• Dorsal arteries of the penis and spongiosal branches
• Renal arteries

Q7. Where is the frenulum located relative to the glans?

• Dorsal midline only
• Ventral surface
• Within the spermatic cord
• Inside the corpus cavernosum

Q8. Which lymph nodes are important first stations for lymph from the glans penis?

• Submental lymph nodes
• Popliteal lymph nodes
• Axillary lymph nodes
• Deep inguinal lymph nodes

Q9. How does lymphatic drainage of the glans differ from much of the penile skin?

• Penile skin drains only to axillary nodes
• Both drain exclusively to lumbar nodes
• The glans has no lymphatic drainage
• The glans favors deep inguinal drainage while penile skin favors superficial inguinal drainage

Q10. Why is the glans highly sensitive?

• It has a rich somatic sensory nerve supply
• It is supplied only by autonomic motor fibers
• It contains motor neurons within its epithelium
• It contains no sensory receptors
