Which term describes movement toward the body’s midline?

The term that describes movement toward the body’s midline is "adduction." This term is used in anatomy to indicate the action of bringing a limb or other body part closer to the central axis of the body. For example, when you lower your arms to your sides after lifting them out to the side, you are performing adduction.

Understanding adduction is crucial in various contexts, such as in physical therapy, sports science, and anatomy. It contrasts with abduction, which refers to movement away from the midline. Knowing these terms helps in communicating effectively about movements and positions in the medical and fitness fields. The other terms, flexion and extension, refer to movements involving bending and straightening of joints, rather than movements toward or away from the midline.
