These terms used in physiology refer to actions that occur at a joint in the body. Flexion usually refers to the part away from the body being brought toward the midline of the body while extension usually refers to the part away from the body being moved away.
As an example when the hand is brought toward the face, flexion occurs at the elbow and when the hand is moved away from the face, extension occurs at the elbow.
