Anatomical terms of bone

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
