Movement – Muscles are attached
to bones
- Bones form joints

Lots of small piece of bone joined
together – they do NOT move
2) Slightly Movable – e.g. Vertebrae –
Small amount of movement but quite
stable
3) Freely Moveable / Synovial – e.g.
shoulder, knee, hip
Gliding – e.g. tarsals and carpals
Hinge – e.g. knee, elbow
Pivot – e.g. neck
Ball and Socket – e.g. shoulder, hip
Saddle – e.g. thumb
