Skeletal System and Joints

Human Skeleton with major bones labeled (axial bones are shaded yellow)
Human Skeleton Front unlabeled

The skeletal system includes all of the bones of the body as well as the ligaments, cartilage, and other connective tissues that connect these bones and allow for flexible movement.  It includes specific bones such as the femur, tibia, and humerus (there are 206 different bones in the average adult human).

We have a skeletal system for support, to allow for flexible movement (muscles do the moving, but the bones and joints allow for movement), and for the storage of minerals like calcium and phosphate as well as energy storage (most long bones store fat in a marrow cavity (medullary cavity)).
