Multiple Choice

Which gland is traversed by the facial nerve within its substance?

The key idea is that the facial nerve runs through the parotid gland. After it exits the skull, the nerve enters the parotid gland and travels within its substance, dividing there into its main branches that supply the muscles of facial expression. The other glands shown do not have the facial nerve running through them, so the parotid gland is the one through which the nerve passes. This intraparotid path is clinically important because procedures or injuries in the parotid region can affect many facial movements.
