Movement of a limb straightening it away from the body is known as what?

The movement of a limb straightening it away from the body is known as extension. This action typically increases the angle between body parts, such as when you straighten your arm or leg after bending it. In the context of joints, extension is crucial for various functional movements and contributes to overall mobility. It allows limbs to return to a neutral or anatomical position after bending, which is vital for maintaining balance, coordination, and performing activities of daily living. Understanding this concept is essential for anyone studying physical therapy, as it relates to rehabilitation and treatment of musculoskeletal injuries.
