Articulates with ethmoid bone (anterior), greater wing (lateral), and occipital bone (posterior) Bony plate with foramina (holes) that transmit olfactory nerves (cn i) Contributes to anterior midline portion of anterior cranial fossa. Characteristic features include cribriform plate, crista galli, and perpendicular plate. Contributes to anterior cranial fossa, nasal cavity, and orbit. Between crest of frontal bone and crista galli. Opening bordered by frontal bone (anterior) and ethmoid bone (posterior) If patent, may transmit vein connecting nasal veins with superior sagittal sinus. Irregularly shaped opening formed by sphenoid, temporal, and occipital bones. Inferior opening is closed in living subjects by fibrocartilage. Internal carotid artery enters posterior wall and ascends into middle cranial fossa. Large opening in inferior part of posterior cranial fossa.
