Well there are two muscles which bend the arm: bending your arm from a straight position to a bent position uses the bicep (Latin name - Bicep Brachii) which is on the topside of your upper arm. Bending your arm from a bent position to a straight position uses the tricep (Latin name - Tricep Brachii) which is on the underside of your upper arm.
