On which side of the forearm is the ulna located?

The ulna is located on the side of the little finger in the forearm. This anatomical positioning is significant as it allows for the ulna to extend from the elbow to the wrist alongside the radius. When the forearm is in the standard anatomical position—where the palm faces forward—the ulna's placement on the medial side (the side closest to the body's center) corresponds directly to the little finger. This relationship is essential in understanding how the bones of the forearm work together to facilitate movement and support the body's structure. The ulna is generally larger at the elbow and tapers towards the wrist, while the radius runs parallel to it on the other side, which is aligned with the thumb. Understanding the position of these bones is crucial for anyone studying anatomy, particularly in contexts like medicine and physiology.
