Anatomically, the model shows a saggital section through the nasal cavity and skull. On the right side of the model you can see the septum with associated vessels and nerves, while the left side of the model depicts the nasal turbinates with associated structures.
At the top of the nasal cavity on the left side is the olfactory area (regio olfactoria) where nerve endings from the optic nerve begin. The model illustrates how these run through the lamina cribrosa (part of the os ethmoidal) as fila olfactoria.
In the mucosa on the left side, the mouth of the sphenoid sinus, the mouth of the ductus nasolacrimalis and the mouth of the eustachian tube (tuba auditoria) in the nasopharynx can also be seen.
In addition, sections of the nasal cartilages and sinuses (sinus sphenoidalis and sinus frontalis) are shown.
