1. Pronation leaves the palms facing forward in the anatomical position.
a. True
b. False
The answer is b, false. Supination leaves the palms facing forward in the anatomical position.
2. During supination, the forearm rotates in which direction?
a. Medially
b. Laterally
c. None of the above
The answer is b, laterally. During supination, the forearm rotates in a lateral direction, which is away from the
body’s midline.
3. In the anatomical position, pronation will leave the palms facing which direction?
a. Toward the back (posteriorly)
b. Toward the front (anteriorly)
c. Facing up (superiorly)
d. Facing down (inferiorly)
The answer is a, toward the back (posteriorly). Although the palms will face down when the elbow is flexed 90
degrees, pronating the forearm in the anatomical position will leave the palms facing posteriorly. Pronation will
leave the thumbs pointing toward the body’s midline.
4. When the elbow is flexed 90 degrees, supination will leave the palms facing which direction?
a. Facing down (inferiorly)
b. Facing up (superiorly)
c. Facing forward (anteriorly)
d. Facing to the read (posteriorly)
The answer is b, facing up (superiorly). Supination rotates the forearm laterally, so when the elbows are flexed
90 degrees, the palms will face up when you supinate. If the elbow was extended, the palms would face forward
in the anatomical position.
5. The thumb is on the same side as which forearm bone?
a. Radius
b. Ulna
c. Humerus
d. Coccyx
