Which bone is referred to as the medial bone of the forearm?

The ulna is identified as the medial bone of the forearm because of its positioning relative to the radius. In anatomical terms, the term "medial" refers to a position closer to the midline of the body. In the forearm, when the palm is facing forward in the standard anatomical position, the ulna is located on the side of the body that is closest to the midline, while the radius is on the lateral side. This anatomical orientation is consistent across the majority of individuals, making the ulna the primary bone referred to as the medial bone of the forearm. Understanding the relationship between these bones is crucial for tasks such as assessing forearm injuries or performing procedures that involve the forearm.
