Intermediate Nerve Supply of the Ureters Quiz

Q1. Which sympathetic pathway contributes fibers to the ureter?

• Optic pathways
• Cranial somatic motor pathways
• Brachial plexus pathways
• Thoracolumbar sympathetic pathways through autonomic plexuses

Q2. Which nerves provide parasympathetic fibers to the lower pelvic ureter?

• Pelvic splanchnic nerves from S2-S4
• Phrenic nerves
• Pudendal nerves as the primary autonomic supply
• Greater splanchnic nerves only

Q3. Which plexus distributes mixed autonomic fibers in the lower pelvis?

• Brachial plexus
• Celiac ganglion only
• Cervical plexus
• Inferior hypogastric plexus

Q4. What is the relationship between sympathetic fibers and ureteric pain afferents?

• Pain afferents commonly accompany sympathetic pathways centrally
• Pain afferents travel only with somatic motor nerves
• Sympathetic fibers carry no associated visceral afferents
• Pain travels exclusively through the vagus nerve

Q5. Why can ureteric pain be felt in the lower anterior abdominal wall?

• The ureter lies within the abdominal skin
• Urine enters cutaneous nerves
• Visceral and somatic inputs converge at shared spinal segments
• The ureter directly innervates skeletal muscle

Q6. Why may distal ureteric pain be perceived in the groin or external genital region?

• Shared spinal segments create referred pain to inguinal and genital regions
• The bladder lies inside the scrotum
• The distal ureter enters the inguinal canal
• The ureter becomes the genitofemoral nerve

Q7. What is the principal role of extrinsic autonomic nerves in ureteric motility?

• They convert smooth muscle into skeletal muscle
• They modulate rather than solely generate peristaltic activity
• They are the only source of every peristaltic wave
• They prevent all ureteric contraction

Q8. Which plexus is most closely associated with autonomic innervation near the kidney and proximal ureter?

• Pulmonary plexus
• Pharyngeal plexus
• Cardiac plexus
• Renal plexus

Q9. Which autonomic network helps connect abdominal and pelvic innervation along the ureter?

• Lumbar somatic plexus alone
• Facial nerve network
• Aortic and hypogastric plexus network
• Brachial and cervical plexus network

Q10. Which statement best describes ureteric innervation?

• Regional autonomic plexuses supply the ureter and visceral afferents convey pain
• The ureter has no sensory innervation
• The ureter is supplied only by somatic motor nerves
• The vagus nerve is the sole nerve of the entire ureter
