What term describes the forearm rotation with the palm facing up?

Explanation:
Supination is the forearm rotation that turns the palm to face up. This occurs as the radius rotates around the ulna so the two bones run parallel rather than crossed. In contrast, pronation is when the radius crosses over the ulna and the palm faces down. The other terms refer to unrelated structures: the tibia is a leg bone, vertebrae are spinal bones, and tinnitus means ringing in the ears. Therefore, the term for forearm rotation with the palm facing up is supination.
