Description

This model presents the anatomical structure of the nose and paranasal sinuses located in the upper right portion of the face, enlarged 1.5 times for enhanced clarity. The external features and surrounding structures are clearly visible, providing a detailed understanding of the nasal and sinus anatomy, differentiated by colour (also visible through the removable transparent skin):

• The outer nasal cartilages
• The nasal, maxillary, frontal and sphenoidal 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)
