Which nerve carries the secretomotor (parasympathetic) fibers to the submandibular gland?
Show answer and explanation
Correct answer: A. Lingual nerve (conveying chorda tympani fibers)
- A. Correct. Parasympathetic fibers travel via the chorda tympani, join the lingual nerve, and synapse at the submandibular ganglion to supply the gland.
- B. The hypoglossal nerve is purely motor to tongue muscles.
- C. The glossopharyngeal supplies the parotid (via the otic ganglion), not the submandibular.
- D. The facial nerve provides the fibers, but they reach the gland via the chorda tympani → lingual nerve route, not directly.
