These full-size human skeletons are a great instructional aid for teaching anatomy. Bones are cast individually from naturally colored plastic with anatomical detail. Both the arms and legs are removable for further study. The skull features movable jaw, removable skullcap, suture lines and a full dentition. All movable parts are joined by connectors, and utilized in such a way to allow movement around the joint. Comes pelvic mounted or hanging on a roller base and supplied with a diagram.
