The human ulna is a long bone that runs from the elbow to the wrist on the opposite side of the radius. It forms the medial side of the forearm and provides attachment points for muscles involved in arm movement. The ulna also protects the median nerve, a vital nerve that supplies sensation to the hand. In addition to its functional role, the ulna is also notable for being one of the longest bones in the human body, measuring around 23-25 centimeters in length.
