Enlarged approx. 3 times, in SOMSO-Plast®. An instructive double model which clearly shows the complicated structure of bones and the nasal cavity covered by mucous membrane. Individual cartilages and bone are coloured. The nasal concha can be removed (entry to the ethmoidal labyrinth is visible). The right side shows the nasal septum (removable) and the mucous membrane of the nasal cavity with the three nasal passages and nasal conchae. The middle concha can be removed so that the olfactory nerve and olfactory lobe can be seen. Separates into 5 parts. On a green base.
