- Celiac ganglia
- Ciliary ganglia
- Geniculate ganglia
Q2. Which thoracic splanchnic nerve commonly provides a major sympathetic contribution to the celiac ganglia?
- Pelvic splanchnic nerve
- Phrenic nerve
- Greater thoracic splanchnic nerve
- Pudendal nerve
Q3. Which plexus surrounds the origin of the superior mesenteric artery and continues along its branches?
- Inferior hypogastric plexus
- Cardiac plexus
- Brachial plexus
- Superior mesenteric plexus
Q4. Which autonomic plexus is closely associated with the renal arteries?
- Sacral somatic plexus
- Renal plexus
- Pharyngeal plexus
- Pulmonary plexus
Q5. Which plexus continues inferiorly from the intermesenteric region toward the aortic bifurcation?
- Aortic plexus
- Cervical plexus
- Brachial plexus
- Submucosal plexus only
Q6. What happens to many preganglionic sympathetic fibers after entering abdominal prevertebral plexuses?
- They become parasympathetic fibers
- They enter the spinal cord without synapsing
- They synapse in prevertebral ganglia
- They synapse in skeletal muscle
Q7. How do many postganglionic sympathetic fibers reach abdominal viscera?
- They travel through the central canal of the spinal cord
- They pass exclusively through the rectus sheath
- They travel only inside veins
- They follow arterial branches in periarterial plexuses
Q8. Where do vagal preganglionic parasympathetic fibers usually synapse?
- In the sympathetic trunk
- In terminal or intramural ganglia near the target organ
- In the celiac ganglion
- In dorsal root ganglia
Q9. Which plexus is an important continuation of abdominal autonomic fibers into the pelvis?
- Cervical plexus
- Superior hypogastric plexus
- Lumbar somatic plexus
- Brachial plexus
Q10. What is the intermesenteric plexus?
- An autonomic network along the aorta between the mesenteric plexuses
- A lymphatic plexus within the mesentery
- A venous plexus inside the liver
- A somatic nerve network within psoas major
