Facial nerve exits the skull via?
A. Foramen ovale
B. Stylomastoid foramen
C. Foramen rotundum
D. Jugular foramen
Correct answer: B. Stylomastoid foramen
- Facial nerve exits the pons and enters the internal acoustic meatus along with acoustic nerve.
- After traversing a short distance in the facial canal, facial nerve exits the skull via stylomastoid foramen and subdivides to supply the facial muscles.
- Hence, injury to facial nerve at stylomastoid foramen paralyses all muscles of facial expression.
