It's one of two forearm bones.
The ulna is the larger of two bones in the forearm. It's on the "pinky" side of the forearm. Thus it is a part of the skeletal system.
The ulna and the radius are the two bones in the forearm. Latin: Ulnaris et. radialis. If you hold your arm at your side with the palm forward ulna is palpable on the medial (inside) part of the forearm, whilst the radius is palpable on lateral (outside) side. In layman terms, the radius is on the side of your thumb, and the ulna on the side of the pinky-finger.
Another name for the forearm is the lower arm. The forearm consists of two bones, the radius and the ulna.
The two bones in the forearm allow it to turn better, so it is not necessary to turn the whole arm in oreder to slightly change the angle of the hand. There are three bones in the human arm (radius, ulna, humerus), so the question needs to be revised. If the question was supposed to be why having two bones in the FOREARM is better than one, then the answer is because having two bones is what allows the forearm to rotate. If there were only one bone in the forearm, then we would not be able to do so.
