1. All fossils recovered from Arago were found by frontal and a sphenoid bone . 2. Some of the fibers also pass through the fissure to the spine of sphenoid bone . 3. Some pituitary adenomas can extend inferiorly, growing downward and invading the sphenoid bone and cavernous sinus. 4. Between the 18th and 25th years the occipital and sphenoid bone become united, forming a single bone. 5. One difficulty was the scarcity of sphenoid bones , which are fragile and often are not preserved in skull fossils. 6. He was the first anatomist to publish descriptions of satisfactory pterygoid process and the sphenoid bone and bone clinoideo tear. 7. The upper head originates from the infratemporal surface and the infratemporal crest of the greater wing of the sphenoid bone . 8. Adenomas greater than 10mm ( macroadenomas ) can cause remodeling of the underlying sphenoid bone altering the shape of the sella turcica. 9. In mammals, the side opening is closed by the sphenoid bone , so that the skull roof appear whole, despite the temporal opening. 10. As the Pituitary gland is in close proximity to the brain, invasive adenomas may invade the dura mater, cranial bone, or sphenoid bone .
