Which movement describes the action of moving a bone toward the midline?

The action of moving a bone toward the midline of the body is known as adduction. This describes a movement where a limb or a body part is brought closer to the center of the body. For instance, when you bring your arms down to your sides or swing your legs together, those movements exemplify adduction.

In contrast, the other terms refer to different types of movement. Abduction is the opposite of adduction; it describes moving a limb or body part away from the midline. Flexion refers to decreasing the angle at a joint, such as bending the elbow or knee. Rotation involves the circular movement around an axis, such as turning your head from side to side. Understanding these terms aids in grasping the mechanics of movements within the body, which is essential in fields related to anatomy and physiology.
