The natural large spine model is made to the real scale of the human body, presenting the entire spine structure from the cervical vertebrae to the coccyx in full. It also includes the pelvis and the base of the occipital bone, clearly showing the morphological characteristics of the vertebral bodies, intervertebral discs, vertebral arches, transverse processes, spinous processes and articular processes.

Models are usually equipped with elastic spinal cord nerves and vertebral artery diagrams, which can demonstrate the distribution of nerve roots and blood supply pathways. The intervertebral discs are made of simulated soft rubber material to restore their buffering and shock-absorbing functions. Some designs can perform dynamic demonstrations such as bending and rotation, facilitating the explanation of the physiological curvature of the spine, the range of motion of joints, and the impact of posture changes on weight-bearing.

In medical teaching, the natural large spine model is an intuitive tool for learning anatomy, orthopedic diseases, scoliosis and intervertebral disc protrusion and other pathologies. In rehabilitation and sports training, it can be used to explain the principles of posture assessment, spinal stability training and injury prevention. Its durable, detachable and easy-to-disinfect features make it suitable for classroom teaching, clinical demonstrations and patient communication, helping the audience deepen their understanding of the structure and function of the spine through three-dimensional observation and repeated operation.

The Natural large Spine model provides a very detailed display of all the major features of each spine, including the vertebrae, nerve roots, spinal arteries, intervertebral discs, transverse processes and cross-sections of the spine. It is an ideal teaching model for chiropractic, plastic surgery and other medical specialties, and also an ideal model for companies in the field of health care.

The main features include: a 29-inch high hard spine, pelvis, sacrum, occipital bone, spinal arteries, nerve arteries and lumbar intervertebral discs, etc. It comes with a 34-inch high-luxury iron seat.
