Q3. Pelvic splanchnic nerves arise from which rami of the sacral spinal nerves?

  • Cervical ventral roots only
  • Posterior rami of S2 to S4
  • Anterior rami of S2 to S4
  • Thoracic dorsal rami

Q4. Which autonomic plexus receives pelvic splanchnic nerve fibers in the pelvis?

  • Cervical plexus
  • Inferior hypogastric plexus
  • Lumbar somatic plexus
  • Brachial plexus

Q5. Which embryologic gastrointestinal territory receives parasympathetic fibers from pelvic splanchnic nerves?

  • Pharyngeal gut only
  • Foregut only
  • Hindgut
  • Midgut only

Q6. Which part of the large intestine receives pelvic splanchnic parasympathetic innervation?

  • Descending colon
  • Ascending colon
  • Cecum
  • Proximal jejunum

Q7. Which additional large-intestinal segment receives pelvic splanchnic parasympathetic fibers?

  • Cecum
  • Sigmoid colon
  • Ascending colon

Q8. Which parasympathetic nerve supplies foregut and midgut derivatives instead of the pelvic splanchnic nerves?

  • Pudendal nerve
  • Femoral nerve
  • Obturator nerve
  • Vagus nerve

Q9. Where do preganglionic pelvic splanchnic parasympathetic fibers generally synapse?

  • In the sympathetic trunk
  • In or near the target organs
  • In dorsal root ganglia

Q10. Which statement correctly distinguishes pelvic splanchnic nerves from sacral splanchnic nerves?
