What does "Supination" mean?

Medial rotation of the joint
Turning the joint cold
Turning the joint downward
Turning the joint upward

The correct answer is: Turning the joint upward

The term "supination" refers specifically to the rotational movement of the forearm and hand that turns the palm upward or forward. This action involves rotating the radius and ulna (the two bones in the forearm) so that the palm faces upward. In the context of anatomy, supination is the opposite of pronation, which involves turning the palm downward. Understanding this term is essential for those in the healthcare field because it plays a significant role in various physical assessments and interventions. Being able to accurately describe and identify movements such as supination is crucial for providing quality patient care, especially in contexts like rehabilitation and physical therapy.
