What movement is defined as turning the palm up?

Turning the palm up is defined as supination. This movement involves rotating the forearm in such a way that the palm faces upward or forward, depending on the position of the body. Supination occurs when the radius and ulna bones of the forearm are parallel to each other, which allows the palm to turn upwards. This movement is essential in various activities, such as holding food items or objects with the palm facing up, and plays a vital role in many exercises and functional movements in sports medicine.

In contrast, pronation is the opposite movement where the palm faces downward. Elevation refers to moving a body part superiorly, such as shrugging the shoulders. Retraction involves moving a body part, typically the scapula, towards the midline of the body. Each of these movements has distinct characteristics and applications, making supination the correct term for turning the palm up.
