This beautifully detailed skeleton from Axis Scientific serves as the perfect tool for studying both the skeletal and muscular systems. It features muscle origin and insertion points painted and numbered on one half, and flexible ligamented joints of the shoulder, elbow, wrist, hip, knee, and ankle on the other. The spine is also flexible, making it a great tool for displaying how the skeletal and muscular systems work together. The arms (attached by a bungee cord) and legs (attached with metal hardware) are movable, and the fingers and toes are flexible. This model uses a pelvic-mounted metal stand on a lightweight plastic, 5-caster wheel base for sturdiness
