Which bone is referred to as the ulna?

• A. A long bone in the thigh
• B. A long bone in the forearm
• C. A bone in the lower leg
• D. A bone in the wrist

Answer: (B)

The ulna is correctly identified as a long bone in the forearm. It is one of the two long bones in this region, the other being the radius. The ulna is located on the opposite side of the radius when the palms are facing forward. It extends from the elbow to the wrist and plays a critical role in the movement and stability of the forearm, particularly in activities that involve bending and extending the elbow. Understanding the ulna’s location and function is essential in fields such as anatomy, kinesiology, and health sciences, as it is integral to the mechanics of the upper limb.
