Here's a great accessory for orthopaedic surgeons, chiropractors, physical therapists and other back specialists. This keychain features three carefully sculpted lumbar vertebrae separated by soft discs that allow them to flex like a real spinal column.
The spine, or backbone is a feat of biological engineering that has allowed the vertebrates to master the rigors of many environments! This marvelous structure protects critical nerves while providing just the right balance of rigidty and flexibility, allowing for movement that is both dexterous and strong.
Every feature, facet and process of these vertebrae is modeled with care, making this an excellent aid de memoire for students, or portable teaching tool for clinicians. Comes with a colorful anatomical diagram.
