Final answer:
The movement in which a bone spins on its longitudinal axis is known as rotation, which includes both medial and lateral rotations.
Step-by-step explanation:
A movement in which a bone spins on its longitudinal axis is known as rotation. This can occur as either medial rotation, where the rotation is toward the midline of the body or lateral rotation, where it is away from the midline. An example of rotation is the movement of the head from side to side, akin to saying "no." This is distinct from other types of joint movements such as flexion, extension, abduction, and adduction, which involve changes in the angle between bones of a joint, or movements away from or towards the body's midline.
