What describes the rotational movement of a bone?

The term that describes the rotational movement of a bone is rotation. This movement occurs around an axis, allowing a bone to twist or turn. For instance, when you rotate your arm at the shoulder, the humerus bone pivots around its axis, showcasing rotation. This type of movement is essential for numerous functional activities, as it facilitates the full range of motion in joints.

Inversion refers specifically to the movement of the foot where the sole turns inward, protraction describes the movement of a body part forward, often used in reference to the shoulder blades, and retraction is the movement of a body part backward. Each of these terms pertains to movements that are not related to rotation, emphasizing that rotation is the most accurate description for this type of movement in bones.
