Greater wings of sphenoid (overview and surfaces)

The greater wings are two large, irregularly shaped projections that extend from either side of the body in the lateral, superior and posterior directions. They not only contribute to the cranial base but also form the posterolateral aspects of the orbits. Moreover, the greater wings also form the lateral walls of the skull, as well as the floor of the middle cranial fossa. Additionally, they contribute to the temporal fossae, infratemporal fossae, and pterygopalatine fossae.
