The image shows a superior view (looking inside) of the bones forming the anterior cranial fossa. The crista galli bony projection of the ethmoid bone is found in the middle of the image. The frontal bones are found laterally. However, the blue arrow indicates the perforated cribriform plate of the ethmoid bone, which allows the passage of the olfactory nerve (CN I) fibres into the brain from the nasal cavity.

Crista galli
QuestionChoice
The image shows a superior view (looking inside) of the bones forming the anterior cranial fossa. The crista galli bony projection of the ethmoid bone is found in the middle of the image. The frontal bones are found laterally. The nasal septum is a wall of bone and cartilage found between the left and the right nostrils. It is not visible in the image because this shows the skull base bones from above. However, the blue arrow indicates the perforated cribriform plate of the ethmoid bone, which allows the passage of the olfactory nerve (CN I) fibres into the brain from the nasal cavity.

Cribriform plate
QuestionChoice
The image shows a superior view (looking inside) of the bones forming the anterior cranial fossa. The crista galli bony projection of the ethmoid bone is found in the middle of the image. The frontal bones are found laterally. The sphenoid bone is located posterior to the bones showed in the image, as it forms part of the middle cranial fossa. However, the blue arrow indicates the perforated cribriform plate of the ethmoid bone, which allows the passage of the olfactory nerve (CN I) fibres into the brain from the nasal cavity.

Sphenoid bone
QuestionChoice
The image shows a superior view (looking inside) of the bones forming the anterior cranial fossa. The crista galli bony projection of the ethmoid bone is found in the middle of the image. The frontal bones are found laterally. The vomer bone is a midline bone of the face, located between the right and left nasal cavities. It is not visible in the image because this shows the skull base bones from above. However, the blue arrow indicates the perforated cribriform plate of the ethmoid bone, which allows the passage of the olfactory nerve (CN I) fibres into the brain from the nasal cavity.
