Beginner Celiac Plexus Quiz

Q1. Where is the celiac plexus primarily located?

• Within the inguinal canal
• Around the origin of the celiac trunk
• Around the external iliac artery
• Inside the rectus sheath

Q2. Which paired sympathetic ganglia are major components of the celiac plexus?

• Ciliary ganglia
• Dorsal root ganglia
• Geniculate ganglia
• Celiac ganglia

Q3. Which thoracic splanchnic nerve is a major source of preganglionic sympathetic fibers to the celiac ganglia?

• Pudendal nerve
• Pelvic splanchnic nerve
• Greater thoracic splanchnic nerve
• Phrenic nerve

Q4. Which parasympathetic nerve contributes fibers to the celiac plexus?

• Ilioinguinal nerve
• Obturator nerve
• Vagus nerve
• Femoral nerve

Q5. Do vagal parasympathetic fibers normally synapse in the celiac ganglia?

• No, because the vagus never enters the abdomen
• Yes, all vagal fibers synapse there
• No, they pass through without synapsing there
• Yes, because the celiac ganglia are parasympathetic

Q6. Which embryologic gastrointestinal territory is most closely associated with the celiac arterial and autonomic distribution?

• Foregut
• Hindgut only
• Distal lower limb
• Pelvic floor only

Q7. How do many postganglionic sympathetic fibers leave the celiac plexus for target organs?

• Through the brachial plexus
• Through the femoral canal
• Through dorsal rami only
• Along periarterial plexuses

Q8. Which organ receives autonomic fibers through branches of the celiac plexus?

• Skin of the forearm
• Quadriceps femoris
• Stomach
• Deltoid muscle

Q9. Which type of sensory fibers can pass through the celiac plexus from upper abdominal viscera?

• Special sensory fibers for vision
• Somatic motor fibers to skeletal muscle
• Visceral afferent fibers
• Branchial motor fibers

Q10. Which clinical procedure targets this autonomic network to reduce severe upper abdominal visceral pain?

• Celiac plexus block
• Femoral nerve block
• Brachial plexus block
• Digital nerve block
