What does the term "abduction" describe in anatomical movement?

The term "abduction" in anatomy refers specifically to the movement of a limb or body part away from the midline of the body. This movement is essential in various physical activities and functional movements, as it allows for the separation of limbs and body parts for a range of purposes, such as increasing the range of motion, performing tasks efficiently, or facilitating certain athletic movements.

For instance, when you raise your arms sideways away from your body, you are performing abduction at the shoulder joint. Similarly, spreading your fingers apart can also be considered abduction at the metacarpophalangeal joints. Understanding this term is crucial for grasping the mechanics of movement in both clinical contexts and physical fitness.
