that makes the ulna the one that extends from your little finger, which is the outer part of the forearm which i was (correctly) referring to
the part I don't get is why you keep saying "outer"
both bones are on one side of the limb either way... they might even cross when the forearm is pronated as the radius is specially designed to rotate at the level of the elbow.
in a regular anatomical position, the ulna faces towards the ribs and body wall - the thumb is pointed away from the body (preaxial border)
