What is the definition of supination?

1. Turning the palms of the hands down

2. Rotating the palms of the hands up

3. Moving the foot outward

4. Bringing the foot inward

The correct answer is: Rotating the palms of the hands up

Supination is defined as the rotational movement of the forearm and hand in which the palms are turned upward or forward. In this position, the radius and ulna, the two long bones of the forearm, are parallel to each other. This term is often used in the context of movements associated with exercise, rehabilitation, and various physical activities. In the context of the foot, although options discussing the inward or outward movement do relate to supination and pronation, the primary anatomical definition links specifically to the position of the palms. Therefore, turning the palms of the hands up captures the essential concept of supination in relation to upper limb movements. The other choices focus on different actions, such as pronation or adduction movements of the foot, which do not accurately reflect the definition of supination in terms of arm and hand positioning.
