biomechanics
1. The science concerned with the action of forces, internal or external, on the living body.
2. The study of the mechanical laws relating to the movement or structure of living organisms.
3. The study of body movements and of the forces acting on the musculoskeletal system.
4. The application of mechanics to the structures of living animals; especially, to the forces on the skeleton caused by the muscles, gravity, and resulting movements of the locomotor system.

Biomechanics is a curious blend of mechanical engineering and biology. It was born of the recognition that parts of a living organism may be viewed as mechanical devices to which engineering concepts; such as, fluid pressure, mechanical stress and friction can be applied.
