Midsagittal skull (with septum) (English)

This section allows the appreciation of the structure of the bony nasal septum, which is composed of the perpendicular plate of ethmoid bone and vomer joining the maxilla and palatine bones. The latter two bones are seen comprising the floor of the nasal cavity, separating it from the oral cavity. At the roof of the nasal cavity there is the ethmoid bone which encloses it towards the anterior cranial fossa. Below, there is a hollow cavity which represents the sphenoidal sinus.
