A long bone is one of the types of bones classified by shape.
bones are longer than they are wide
i.e. length > diameter.
They consist of a shaft - which is the main (long) part and
a variable number
of endings (extremities), depending on the joints formed at one or both ends of the long bone.
Long bones are usually somewhat curved - contributing to their mechanical strength.
