The sphenoid bone has a sella turcica, which is a depression in its superior surface that holds the pituitary gland. It also has optic foramen, which is a passage for the optic nerve to enter the orbit. The wings of the sphenoid bone also form parts of the lateral walls of the orbit. The zygomatic bone forms the prominence of the cheek and does not contain the structures mentioned. The ethmoid bone forms parts of the nasal septum and the medial wall of the orbit, but does not have these specific features. The temporal bone forms the side of the skull, but does not have these specific features. The frontal bone forms the forehead and roof of the orbits, but does not have the wings or optic foramen.
