Question

Flexors reduce the angle at the joint. An example of a flexor muscle is the bicebs brachii, which, when they contract, reduce the angle of your elbow joint, bringing your hand towards your shoulder.
Extensors increase the angle at the joint when contracted. Your triceps brachii are extensors as they increase the angle at the elbow joint, extending your hands towards your hips.
Abductors draw a limb away from the midline. For example, the abductor muscles of the legs spread the legs away from the midline and away from one another (like doing a split) when contracted.
Adductors return the limb back toward the body. The groin muscles (the adductor magnus, adductor longus, adductor brevis, pectineus, and gracilis) are adductors. When contracted, they pull the legs back to the midline and back together.
The diagrams below serve as a visual reference for flexors, extensors, abductors, and adductors.
