The anterior cranial fossa is bounded anteriorly and laterally by the frontal bone, inferiorly by the orbital plate of the frontal bone, the cribriform plate, and crista Galli of the ethmoid bone, and by the lesser wings and the anterior aspect of the body of the sphenoid. Borders The borders of the anterior cranial fossa are the following: anterior and lateral: the inner surface of the frontal bone; posteromedial: limbus of the sphenoid bone; posterolateral: lesser wings of the sphenoid bone; inferior: an orbital plate of the frontal bone, cribriform plate and crista Galli of the ethmoid bone, anterior aspects of the body, and lesser wings of the sphenoid bone. Contents The anterior cranial fossa contains the following parts of the brain: the frontal lobe of the cerebral cortex, olfactory bulb, olfactory tract, orbital gyri. Openings There are several openings connecting the anterior cranial fossa with other parts of the skull, and these are the following: anterior ethmoidal foramen, cribriform foramina. The paired anterior ethmoidal foramen connects the anterior cranial fossa with each orbit and transmits the anterior ethmoidal artery, nerve, and vein. The cribriform foramina are the openings in the cribriform plate of the ethmoid bone, which connect the anterior cranial fossa with the nasal cavity and transmit the olfactory nerves. #anteriorcranialfossa #interioroftheskull #cranialfossa #anatomy #osteology #skullanatomy #anteriorcranialfossaanatomy #anteriorcranialfossaboundaries #anteriorcranialfossaborders #anteriorcranialfossacontents #anteriorcranialfossaanatomy #anteriorcranialfossa #anteriorcranialfossaanatomy
