Larynx with Bronchial Tree and Transparent Lungs
This unique model was created on the basis of computer tomography data
of a human (male, approx. 40 years). What is special about this procedure
is that the natural spatial 3D relationships and the reciprocal location of
the segmental bronchi can be preserved and depicted in a realistic way.
The larynx with hyoid bone and epiglottis and the trachea with primary
and lobar bronchi are shown in one colour. The larynx is detachable at the
level of the second tracheal cartilage and divisible in the median plane.
The epiglottis is mounted flexibly. The various segmental bronchi are made
of elastic material and detailed in various transparent colours so that they
are easier to distinguish visually. The transparent lungs are detachable.

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 times enlargement. The following
structures can be seen from the outside, 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)
