The jugular tubercle (of occipital bone) is a rounded prominence: 568 /oval elevation upon the superior (i.e. internal) surface of the occipital condyle: 817 at the junction of the basilar part and lateral part of the occipital bone, just medial to the jugular foramen: 568 on either side of the foramen magnum.
It overlies (i.e. is situated superior to: 568 ) the hypoglossal canal: 817 and is situated anterosuperior to the internal opening of this canal. 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.: 568
