What are the major bones of the arm?

The major bones of the arm are accurately identified as the humerus, radius, and ulna. The humerus is the long bone that runs from the shoulder to the elbow, forming the upper arm. The radius and ulna are the two long bones of the forearm; the radius is located on the thumb side, while the ulna is on the side opposite the thumb. Together, these three bones create the skeletal framework of the arm, allowing for a range of motions and supporting muscular attachment necessary for various activities.

The other options include bones or muscle names that do not accurately represent the major bones of the arm. For instance, the femur is a bone found in the thigh, and neither the bicep brachii nor the tricep brachii are bones; they are muscles of the upper arm that aid in movement but do not constitute the skeletal structure of the arm. Recognizing the correct terms and their respective functions is crucial in understanding human anatomy, particularly in the context of kinesiology and fitness.
