Martial Arts Instructor (MAI) Course Test 1 Practice

Think about which bones belong to the upper limb. The arm is made up of the humerus in the upper part, plus the two forearm bones, radius and ulna. The tibia, however, is a leg bone located in the lower leg (the shin). So the tibia is not a bone of the arm, which makes it the correct choice. Radius and ulna run on the forearm with the radius on the thumb side and the ulna on the pinky side, while the humerus connects the shoulder to the elbow.
