The idea
Bones are classed by shape as long, short, flat, irregular or sesamoid.
In practice
The femur and humerus are long bones; wrist and ankle bones are short; the skull, ribs and sternum are flat; vertebrae are irregular; sesamoid bones form inside tendons.
Where people slip
The classes describe shape, not size: finger bones are small but still long bones.
