Basilar part

Basilar Part

The Basilar Part (pronunciation: /ˈbæsɪlər pɑːrt/) is a term used in anatomy to refer to the portion of the occipital bone that lies anterior to the foramen magnum and is part of the cranial base.

Etymology

The term "basilar" is derived from the Latin word "basis" which means "base". The term "part" is derived from the Latin word "partem" which means "portion".

Anatomy

The basilar part is quadrilateral in shape and connects the sphenoid bone to the rest of the occipital bone. It is marked by the pharyngeal tubercle which gives attachment to the superior pharyngeal constrictor muscle. The basilar part also forms a joint with the sphenoid bone known as the basilar synchondrosis.
