This full-size human skeleton is a great instructional aid for teaching anatomy. Carefully cast in durable molding with naturally colored plastic, each model is painted to realistically display the muscle origins in red and muscle insertions in blue. Each muscle is accurately painted and numbered. The arms and legs are joined by connectors and can be moved to demonstrate natural movement around the joints. Both the arms and legs are removable for further study. The skull features a moveable mandible, removable skullcap, suture lines and a full dentition. Comes on a roller base and supplied with diagram.
