A set of 5 life-size models illustrating different types of joint. The examples shown are sutures in the skull, tooth socket, ball and socket hip joint, cartilaginous joint between two vertebrae, and the tibia-fibula joint. The tooth is attached to a jaw which is cut away to show molar roots. The vertebral disc is of natural appearance and flexible, as is the tibia-fibula joint. The hip joint is carefully painted.
