When describing function, flexors are muscles that tend to close the angle between the two bones to which they are attached. Extensors tend to increase the angle.
What do the flexors and extensors control?
Muscles can pull bones, but they cannot return them to their original positions. Therefore, they work in pairs of flexors and extensors. The flexors contract and bend the limbs of the joints. Then, when the movement is complete, the flexors relax and the extensors contract, stretching and stretching the limbs at the same joint.
