This unique model was created on the basis of computer tomography data of a human (male, aprox, 40 years) * What is special about this procedure is that the natural spatial 3D-relations and the reciprocal location of the segmental bronchi can be preserved and demonstrated in a realistic way * 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 various transparent colors so that they are easier to distinguish visually
