The musculoskeletalsystem (MSK) is an organ system that gives animals the ability to physically move, by using the muscles and skeletalsystem.
The humanmusculoskeletalsystem consist of the human skeleton, made by bones attached to other bones with joints, and skeletal muscle attached to the skeleton by tendons.
In most animals with solid skeletons, yellow bone marrow is used to store energy for the muscles and the red marrow produces blood cells and that produces oxygen for the body.
