Anatomical terms of bone[edit on Wikidata]

The pharyngeal tubercle is a part of the occipital bone of the head and neck. It is located on the lower surface of the basilar part of occipital bone. It is the site of attachment of the pharyngeal raphe.

Structure

The pharyngeal tubercle is located on the inferior surface of the basilar part of occipital bone. This about 1 cm anterior to the foramen magnum.

The pharyngeal tubercle gives attachment to the pharyngeal raphe and, thereby, the superior pharyngeal constrictor muscle which forms it.
