Sphenoid Bone and Butterfly

China medical students drew the sphenoid bone in the second anatomical drawing competition, the student combine the sphenoid bone with the butterfly, great idea! The sphenoid clearly shows lesser wing, aperture of sphenoidal sinus, frontal margin, supraorbital fissure, optic foramen, teamporal surface, etc. Awesome teaching aid for medical education!
