The term "adduction" refers to what kind of movement?

1. Movement away from the midline

2. Movement towards the midline

3. Movement in a circular motion

4. Movement in a straight line

The correct answer is: Movement towards the midline

Adduction refers specifically to the movement of a limb or body part toward the midline of the body. This term is used frequently in anatomy and kinesiology to describe how body parts move in relation to one another, particularly in the context of the limbs. For example, when raising an arm laterally and then bringing it back down to the side of the body, that motion involves adduction, as the arm moves closer to the central line of the body. In contrast, movement away from the midline is described by the term "abduction," and other movements, such as circular or straight-line motions, do not pertain to the concept of how body parts relate to the midline. Thus, understanding adduction is essential for recognizing how movements affect body positioning and function, particularly in activities like sports or physical therapy.
