Which of the following bones is located in the arm?

The humerus is the bone that is located in the arm. It is the largest and longest bone of the upper limb, extending from the shoulder to the elbow. The humerus plays a critical role in forming the shoulder joint with the scapula (shoulder blade) and the elbow joint with the radius and ulna. Its structure includes several features that allow for the attachment of muscles, facilitating movement of the arm. The other options, such as the fibula, clavicle, and patella, are associated with different parts of the body; the fibula is found in the lower leg, the clavicle is part of the shoulder girdle, and the patella is the kneecap in the knee joint, all of which are not located in the arm.
