The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
The flex
Paralysis of the quadriceps femoris muscle would make an individual unable to flex the thigh. This muscle is responsible for extending the knee and flexing the thigh at the hip joint.
This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip. Injury to the rectus femoris muscle may result from overuse, as seen with kicking- or sprinting-related injuries. Inflammation of the muscle causes pain in the groin during physical exercises that use this muscle.
The best example is when you flex your arm to make the biceps look large. "Make muscle" it is sometimes called.
