Final answer:
The statement is false; a pronated grip actually has the palms facing down or backward, not up.
Step-by-step explanation:
The statement 'A pronated grip would be palms up' is FALSE. Pronation refers to the forearm motion that rotates the radius over the ulna, resulting in the palm of the hand facing backward or downward when the arm is extended.
This contrasts with supination, which is the motion that turns the palm to face forward or upward when the arm is in the same extended position.
Specifically, in the anatomical position, where the upper limbs are held next to the body, a supinated forearm has the palm facing forward, and the bones of the forearm (radius and ulna) are parallel.
Conversely, a pronated forearm has the palm facing backward or toward the body if the arm is alongside the body, and the radius and ulna form an X-shape.
