Bones are classified according to their shape, and are categorised as either long, short, flat or irregular.
- Long– longer than they are wide eg femur
- Short– the same length as width eg patella or carpal bones
- Flat– flattened width bones eg ribs or skull
- Irregular– bones that don’t fit into any other category and connect other bones together eg pelvis
- Sesamoid are a type of irregular bone that fit around or between tendons eg pisiform bone in the wrist carpals
