Which movement is described as adduction?

Adduction is defined as the movement of a body part toward the midline of the body. This term is commonly used in anatomy and physical fitness to describe actions such as bringing the arms or legs closer together after they have been extended away from the body's center. For instance, when you lower your arms from a T-pose back to your sides, you are performing adduction.

The other options describe different types of movements: moving away from the midline refers to abduction, raising the foot is not specific to midline movement and instead relates to dorsiflexion or plantarflexion depending on the motion involved, and decreasing the angle of a joint characterizes flexion. Understanding these distinctions is key in anatomy and physiology, particularly when discussing body mechanics or rehabilitative exercises.
