Cranial Nerve X - Vagus Page 5 of 24

Intracranial Course

Upon emerging from the lateral aspect of the medulla the branchial motor component travels with the fibers of the accessory nerve (CN XI) into the jugular foramen of the skull. The remaining components of the vagus nerve also enter the jugular foramen and give rise to two ganglia (the superior and inferior vagal ganglia) within the jugular foramen. The branchial motor fibers join with the rest of the vagus nerve just below the inferior vagal ganglion.

All fibers of CN X exit the skull via the jugular foramen.
