This model is a life-size, flexible, anatomical model of the human vertebral column designed for medical education and patient demonstrations. It has a hand-painted muscle markings, which indicate points of muscle origin (red) and insertion (blue). The model provides a comprehensive representation of the spinal column and associated structures:
- Vertebral Column: A fully flexible 29-inch (approximately 74-75 cm) tall spine that allows for the demonstration of natural movement and pathological curvatures.
- Musculature: The left side of the spine features painted muscle attachments, often numbered for easier identification during study.
- Nervous & Vascular Systems: Includes representations of the spinal cord, spinal nerve branches, and the vertebral artery.
- Pelvic Region: Features a complete male pelvis, including the sacrum, coccyx, and symphysis.
- Clinical Details: Specifically illustrates a prolapsed (herniated) intervertebral disc, typically located between the L3 and L4 or L4 and L5 vertebrae.
- Material: Constructed from durable, washable, and unbreakable synthetic PVC.
- Total Height: Approximately 82 cm to 86 cm when mounted on its stand.
- Weight: Roughly 2.5 kg to 2.9 kg.
- Display: Typically supplied with a chrome metal stand (approx. 34 inches high) with a hanging hook, from which the spine can be easily removed for hands-on study.
