What is the name of the long bone located in the upper half of the arm?

• A. Radius
• B. Ulna
• C. Humerus
• D. Clavicle

Answer: (C)

The long bone located in the upper half of the arm is called the humerus. This bone is crucial as it connects the shoulder to the elbow and plays a significant role in upper arm movement. Specifically, the humerus allows for a wide range of motions, including lifting and swinging the arm, which enables various activities such as throwing or reaching. In contrast, the radius and ulna are bones that form the forearm, positioned between the elbow and the wrist. The clavicle, commonly known as the collarbone, is not located in the arm itself but rather serves as a structural support connecting the arm to the body at the sternum. Understanding this anatomical structure helps in grasping the functionality of the arms and their components.
