The movement of a limb or body part away from the mid-line of the body is known as abduction. This term specifically describes the action where the angle between the limb and the mid-line increases, leading to a wider stance or positioning relative to the center of the body. For example, when you raise your arms sideways away from your body or move your leg out to the side, those movements are classified as abduction.

Understanding the terminology and direction of movement is crucial in fields like kinesiology, as it forms the foundation for analyzing body mechanics, developing movement strategies, and creating exercise plans that target specific muscle groups in a safe and effective manner.

The other options refer to different movements or concepts that do not accurately describe the movement away from the mid-line.
