Detailed Human Lumbar-Sacral Spine and Spinal Nerves Model for Study

The model is designed to study the human spine. The model reproduces the human spine from L1 to the sacrum with flexible intervertebral discs
The material of vertebrae imitates bone tissue
the outer shell is made of hard polymer material, imitating the cortical layer of bone
inside - imitation of spongy bone structure
The model contains an anterior longitudinal ligament covering the anterior surface of vertebral bodies and intervertebral discs along their entire length.
A posterior longitudinal ligament runs along the posterior surface of the vertebral bodies of the model in the same manner
