Q1. What type of nerve supply does the ureter primarily receive?
- Phrenic nerves only
- Autonomic nerves with visceral afferent fibers
- Special sensory nerves only
- Somatic motor nerves only
Q2. Which autonomic plexus contributes fibers to the upper ureter?
- Cervical plexus
- Sacral somatic plexus
- Brachial plexus
- Renal plexus
Q3. Which plexus contributes fibers to the abdominal ureter as it descends?
- Parotid plexus
- Brachial plexus
- Cardiac plexus
- Aortic plexus
Q4. Which plexus is an important source of autonomic fibers to the pelvic ureter?
- Lumbar somatic plexus only
- Hypogastric plexuses
- Cervical plexus
- Brachial plexus
Q5. What type of muscle forms the contractile wall of the ureter?
- Cardiac muscle
- Skeletal muscle
- Smooth muscle
- Striated sphincter muscle only
Q6. Are ureteric peristaltic waves completely dependent on extrinsic autonomic nerves?
- No, ureteric peristalsis is primarily myogenic
- Yes, every wave begins in the spinal cord
- No, because urine moves only by gravity
- Yes, every wave requires a somatic motor impulse
Q7. Which fibers carry pain sensation from the ureter?
- Optic nerve fibers
- Visceral afferent fibers
- Somatic motor fibers
- Special taste fibers
Q8. Ureteric pain commonly refers from the loin toward which region?
- Occiput
- Shoulder
- Groin
- Palm
Q9. Which spinal cord levels are classically associated with ureteric pain afferents?
- S4-Co1 only
- T11-L2
- C1-C4
- T1-T4 only
Q10. Why can a ureteric stone cause severe colicky pain?
- The ureter contains no sensory fibers
- Distension and smooth-muscle spasm activate visceral afferents
- The stone directly compresses the brain
- The stone stimulates skeletal muscle inside the ureter
