The sphenoid bone is the most complex bone of the human body. Because of its shape, it is also known as the “wasp bone”. The sphenoid bone makes up most of the middle part of the base of the skull.

There are four main parts to the sphenoid bone:
the body, which is the most centrally positioned portion of the sphenoid bone. Anteriorly, it contributes to the nasal cavity. Laterally, it builds the medial wall of the optic canal.
the lesser wings project laterally from the superior aspect of the body;
the larger greater wings make up the most lateral part of the sphenoid bone;
and finally, the pterygoid processes which project inferiorly from the body.

Throughout the full version of this tutorial, we’ll first look at the specific bony features on each of these parts of the sphenoid bone. We’ll then look at those features in an image of the skull, to see their relationship to other bones and features of the skull.
