Joints and Bones
Anatomy models of human joints are widely used in both education and in medical practice. You can demonstrate both the structure of the joint and the joint movement, the level of movement depends on the model you use and as a general rule you need to decide if you want a model to demonstrate structure or movement, the more expensive anatomical joints tend to have more movement and more detail, the description of each anatomy joint will help guide you. Anatomical models represent ball and socket joints, hinge joints, gliding joints and others.
You can also buy individual bones, these are useful for specific study, particularly for forensic study or for indepth study of specific areas of the human body. Most individual human bones are life size, although some of the smaller bones of the body can be bought in enlarged sizes.
