technical field

The invention relates to the technical field of human spine demonstration models, in particular to a human spine demonstration model in ice and snow sports.

Background technique

The adult spine is composed of 26 vertebrae connected by ligaments, joints and intervertebral discs. The upper end of the spine supports the skull, the lower part of the hip bone, the middle attached rib, and serves as the back wall of the thorax, abdominal cavity and pelvis. And the function of sports, especially in ice and snow sports, the human spine supports people to complete various turns and jumps, and constantly adjusts the angle as people move to provide people with the best support and protection, reducing the impact on human body functions. To demonstrate the damage to the human spine model, we can observe the movement state of the spine more intuitively and clearly.
