G23 CT Bronchial Tree with Larynx
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 relations and the reciprocal location of the
segmental bronchi can be preserved and demonstrated in a realistic way. Traditional procedures such as
casts from a specimen or completely new models are always at the expense of the natural three dimensions.
The larynx with hyoid bone and epiglottis and the trachea with primary and lobar bronchi are depicted in
one color. 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 depicted in various transparent colors so
that they are easier to distinguish visually.

The three-part model is mounted in its natural position on a base (detachable).
Instructions for care:
• Avoid excessive heat, e.g. prolonged direct exposure to sun.
• Clean the model with a dust brush or with mild soap solutions.
