Correct answer: A. IX & VII cranial Nerves
- A. IX & VII cranial Nerves
- B. V & IX cranial Nerves
- C. V & X cranial Nerves
- D. IX & X cranial Nerves
Explanation
Parasympathetic secretomotor fibres to the salivary glands arise from cranial nerves VII and IX: facial nerve fibres supply submandibular and sublingual glands, while glossopharyngeal fibres supply the parotid gland. The trigeminal nerve mainly provides routes for these fibres rather than originating them.
