A life-size model of the human spine with a removable pelvis. For better distinction, the individual spine sections - cervical, thoracic and lumbar - are designed in different colors. The model is mounted on a flexible metal spiral rod, which makes the spine stable and at the same time very flexible. The perfect model for anyone who wants to work intensively with the spine for many years. Special flexible intervertebral discs behave like natural. The model also has spinal nerves and vertebral artery and a base with a tripod. Individual segments of the spine have flexible intervertebral discs made of special foam, which squeeze on one side and expand on the opposite side, as in natural conditions. Flexible intervertebral discs prevent an unnatural gap between the vertebral body and the intervertebral disc when the spine is bent. All bone parts are cast from the natural spine and show anatomical details such as crevices, appendage holes, furrows, nodules. Due to to the use of an unbreakable, flexible metal rod, the spine is permanently elastic. This model is ideal not only for learning anatomy, demonstrating the curvature of the spine and scoliosis, but also for manual therapy for studying research and mobilization in two and three-dimensional bolts. Flexible intervertebral discs, outgoing spinal nerves and natural motility very well show the interaction between the intervertebral disc, vertebra and nerves. The sacrum is movable in a natural range - approx. 2 degrees of mobility. The pelvis can be removed.
