The sphenoid bone is located where?

The sphenoid bone is one of the skull bones and is located relatively deep within the skull. It is only very slightly visible from an exterior view of the skull. Looking side on to a skull it is right between the temporal bone and the zygomatic bone, in other words it is the small section beneath the Pterion. It is also visible when looking into the orbit (with the eye removed) as the bone with the superior orbital fissure through it.
