What movement describes a forearm position where the palm faces upward?

• A. Pronation
• B. Supination
• C. Flexion
• D. Extension

Answer: (B)

The movement that describes the forearm position where the palm faces upward is known as supination. In the anatomical position, supination occurs when the forearm is rotated so that the palm is oriented upward or forward, depending on the body's position. This action is commonly seen when holding a bowl of soup, which is a helpful mnemonic for remembering that "supination" sounds like "soup." In contrast, pronation is the rotation of the forearm allowing the palm to face downward or backward. Flexion and extension refer to movements that change the angle between body parts, such as bending and straightening a joint. In this context, they do not pertain to the orientation of the palm. Therefore, the correct description of the palm facing upward is accurately defined as supination.
