The basilar part of occipital bone is located directly posterior towards the body of the sphenoid in the midline. It spreads out posteriorly towards the foramen magnum and via the temporal bones is bounded laterally. The pharyngeal tubercle is protuberant on the basilar portion of the occipital bone and is a bony protrusion for the [...]
