A muscle can do one of two things: it can contract, or it can relax. If the muscle is connected by tendons to bones, it will then pull on those bones when it contracts, and it will stop pulling on them when it relaxes. The arrangement of bones and muscles in the human arm allows muscles to bend the arm, by contracting. Also, muscles work in pairs. One muscle bends the arm while another straightens it out again. A single muscle can only pull in one direction, so you need a combination of muscles to be able to move around in a useful manner.
