Which bone is located in the upper arm?

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

Answer: (C)

The upper arm is made up of a single long bone called the humerus. It runs from the shoulder to the elbow, acting as the main support for arm movement and providing attachment points for upper-arm muscles. Radius and ulna are the two long bones of the forearm, extending from the elbow to the wrist; the radius is on the thumb side and can cross over the ulna during rotation. The femur is the thigh bone, located in the leg and connecting the hip to the knee. So, for the bone located in the upper arm, the humerus is the correct one.
