What describes horizontal abduction?

Horizontal abduction refers to the movement of a limb away from the midline of the body in a horizontal plane. This occurs when the arm or leg is lifted sideways while remaining parallel to the ground. In this motion, the angle increases between the limb and the midline, effectively moving the limb outward.

Understanding the concept of planes and movements is crucial in assessing how different body parts can move relative to each other. In contrast, movements towards the midline would be classified as adduction. Rotation and full circular movements refer to different types of motion that do not specifically describe horizontal abduction. Thus, the description provided captures the essence of this movement accurately, making it the correct choice.
