Then, the nerve continues its path along the inside of the skull in the direction of the jugular hole and then leaves the skull next to the glossopharyngeal nerve (IX) and the vagus (X).
Thus, the accessory nerve enters and leaves the skull again, characterized by being the only cranial nerve which has this behavior.
