What characterizes the movement referred to as adduction?

Adduction is characterized by movement towards the midline or center of the body. This means that when a limb or body part moves closer to the body's central axis, it is undergoing adduction. For example, bringing your arms down to your sides from a raised position involves adduction of the shoulders. The term specifically applies to movements within the frontal plane, which divides the body into anterior and posterior sections.

In contrast, options focusing on movement away from the center, rotational movement, or circular movement do not fit the definition of adduction. Such movements are categorized distinctly in anatomical terms; for instance, abduction refers to movement away from the midline, while rotation and circular motion describe different mechanics concerning joints and movement patterns. Adduction is essential for various body movements and is commonly seen in physical activities and exercises that require control and stabilization of limbs towards the body.
