Nose with paranasal sinuses, 5-part

This model illustrates the structure of the nose with the paranasal sinuses in the upper right half of a face in 1.5-fold enlargement.

The following structures can be seen from the outside, differentiated by color (also visible through the removable transparent skin):

• The outer nasal cartilages
• The nasal cavity, maxillary, frontal and ethmoid sinuses
• The opened maxillary sinus when the zygomatic arch is removed

The following structures are shown in a median section:

• The nasal cavity, lined with mucosa, with the nasal conchae (removable)
• The arteries of the mucous membrane
• The olfactory nerves
• The innervation of the lateral wall of the nasal cavity, the nasal conchae and the roof of mouth (palate)
