What is meant by "extension" in the context of body movements?

• A. The movement away from the anatomical position
• B. The return of body parts to the anatomical position
• C. Upward lifting of body parts
• D. Downward movement of the body parts

Answer: (A)

Extension is the action of straightening a joint, which increases the angle between the two bones involved. It typically moves a limb from a bent or flexed position toward a straight or neutral alignment. In everyday terms, you extend a joint when you straighten it rather than bend it. The option reflects this idea by describing extension as movement away from the non-straight configuration, i.e., away from the bent state toward the straight position. The other options describe different movements (flexion is bending to decrease the angle, while upward or downward movements don’t define extension).
