A model of the spine with the chest, occipital bone, vertebral arteries, spinal cord, spinal nerves and movable chest. Intervertebral discs are made of special foam so that they behave like natural. Individual rings have been mounted on a flexible telescope, which makes this model very durable and at the same time mobile. The method of connecting ribs with the sternum and spine allows imitation of natural chest movements as well as the structure and function of the rib-vertebral and rib-sternal joints. The model also allows you to perform asymmetrical movements due to a special combination of the chest with the cartilage of the ribs. This functional model is suitable for physiotherapists, masseurs, music schools and for specialized courses in "first aid".
