Which bone is the uppermost and largest bone of the arm?

Explanation:
The main bone of the upper arm is the humerus. It spans from the shoulder to the elbow, making it the uppermost segment of the arm and the largest bone there. Radius and ulna are in the forearm, between elbow and wrist, while the scapula belongs to the shoulder girdle and is not considered part of the arm itself. So, among these bones, the humerus is the upper arm bone and the largest.
