The jugular tubercle (of occipital bone [1]) is a rounded prominence [2]: 568 /oval elevation [1] upon the superior (i.e. internal [1]) surface of the occipital condyle [2]: 817 at the junction of the basilar part and lateral part of the occipital bone, just medial to the jugular foramen [2]: 568 [1] on either side of the foramen magnum. [1]
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
