Put it about 3 times. An instructive dual model that clearly shows the complex structure of the bones and the nasal cavity covered by mucosa. Individual cartilage and bones are colored. The turbinate can be removed (the labyrinth into the sieve tube is visible). The right side shows the nasal septum (removable) and nasal mucosa, with three nasal passages and turbinates. The middle ear concha can be removed so that the olfactory nerve and olfactory lobe can be seen. Divide into 5 portions. At a base.
