The skeleton gives the body its distinctive shape and provides a supporting framework for all other parts of the body. The bones are linked at joints that are operated by the skeletal muscles. The joints are designed to transmit forces and allow joint movement, usually simultaneously. The magnitudes and types of forces transmitted at the joints and the types and ranges of movement that occur in the joints are refl ected in the size and shape of the bones. The purpose of this chapter is to describe the bones of the skeleton and, in particular, the features of the bones associated with force transmission and joint movement.
