Q1. From which thoracic sympathetic levels does the greater splanchnic nerve most commonly arise?
- T1 to T4
- L1 to L4
- T10 to T11
- T5 to T9
Q2. What type of autonomic efferent fibers predominate in the greater splanchnic nerve?
- Preganglionic parasympathetic fibers
- Somatic motor fibers
- Preganglionic sympathetic fibers
- Postganglionic parasympathetic fibers
Q3. From which structure is the greater splanchnic nerve formed?
- Lumbar plexus
- Thoracic sympathetic trunk
- Phrenic nerve
- Vagus nerve
Q4. In which direction does the greater splanchnic nerve travel after forming in the thorax?
- Inferomedially toward the diaphragm
- Laterally into the upper limb
- Superolaterally toward the axilla
- Anteriorly into the sternum
Q5. Which prevertebral ganglia are the principal synaptic destination of many greater splanchnic nerve fibers?
- Ciliary ganglia
- Dorsal root ganglia
- Otic ganglia
- Celiac ganglia
Q6. Which abdominal autonomic plexus is closely associated with the termination of the greater splanchnic nerve?
- Cervical plexus
- Sacral somatic plexus
- Celiac plexus
- Brachial plexus
Q7. Do most preganglionic sympathetic fibers of the greater splanchnic nerve synapse in the thoracic sympathetic trunk before entering the nerve?
- No, they pass through the sympathetic trunk without synapsing
- Yes, all of them synapse in the thoracic trunk
- Yes, they become parasympathetic there
- No, because they never enter the sympathetic trunk
Q8. Which embryologic gastrointestinal territory is strongly associated with sympathetic fibers relayed through the celiac ganglia?
- Lower limb
- Foregut
- Pelvic floor only
- Hindgut only
Q9. What type of sensory fibers may accompany the greater splanchnic nerve toward the spinal cord?
- Visceral afferent fibers
- Branchial motor fibers
- Special sensory fibers for vision
- Somatic motor fibers to quadriceps
Q10. Which nerve is generally located inferior to the greater splanchnic nerve and arises from lower thoracic levels?
- Pelvic splanchnic nerve
- Lesser splanchnic nerve
- Vagus nerve
- Phrenic nerve
