In a facial drooping case, which nerve is responsible and through which foramen does it exit the skull?
Show answer and explanation
Correct answer: C. Facial nerve (VII) — stylomastoid foramen
Facial drooping = facial nerve (CN VII) paralysis. CN VII exits via the STYLOMASTOID foramen. It then enters the parotid gland and divides into temporal, zygomatic, buccal, marginal mandibular, and cervical branches. Source confirms: 'c. VII' and 'c) Stylomastoid.'
- A. Glossopharyngeal CN IX = posterior tongue/pharynx, exits jugular foramen — not facial drooping.
- B. Vagus CN X = larynx/pharynx/autonomic, exits jugular foramen — not facial movement.
- C. CORRECT. Facial nerve CN VII → stylomastoid foramen → facial drooping. Correct nerve-foramen pair.
- D. Trigeminal CN V = sensation; exits via multiple foramina (V1,V2,V3). Not the cause of facial drooping.
