Q4. Which statement correctly distinguishes sacral splanchnic nerves from pelvic splanchnic nerves?
- Sacral splanchnic nerves are sympathetic, while pelvic splanchnic nerves are parasympathetic
- Both are purely somatic nerves
- Sacral splanchnic nerves are parasympathetic, while pelvic splanchnic nerves are sympathetic

Q8. Which structure gives rise to both right and left sacral sympathetic trunks?
- Continuation of the vagus nerves
- Continuation of the femoral nerves
- Continuation of the pudendal nerves
- Continuation of the sympathetic trunks
Q9. Sacral splanchnic nerves pass from the sympathetic trunks toward which general location?
- Cervical spinal cord
- Pelvic autonomic plexuses
- Popliteal fossa
- Brachial plexus
Q10. Are sacral splanchnic nerves the same as pelvic splanchnic nerves?
- Yes, both are somatic motor nerves
- Yes, both arise from the vagus nerve
