It overlies (i.e. is situated superior to[2]: 568 ) the hypoglossal canal[2]: 817 and is situated anterosuperior to the internal opening of this canal.[1] The glossopharyngeal nerve (CN IX), vagus (CN X), and accessory (CN XI) pass across the posterior portion of the jugular tubercle to reach the jugular foramen.[2]: 568
