2023年10月30日 · The ulna is the medial bone of the forearm and the longer of the two parallel forearm bones. Like the radius, the ulna also has three main parts: a proximal end, shaft and a distal end. The proximal end articulates with the distal humerus and the head of the radius.

2025年1月28日 · The ulna is a long bone of the forearm, situated on the medial side (the side closest to the body when in anatomical position). [3] It consists of three main parts: the proximal end, the shaft, and the distal end.

2023年7月24日 · The ulna is one of the two forearm long bones that, in conjunction with the radius, make up the antebrachium. The bone spans from the elbow to the wrist on the medial side of the forearm when in anatomical position. In comparison to the radius, the ulna is described to be larger and longer.

2025年1月31日 · Explore the anatomy and function of the ulna with Innerbody's interactive 3D model. The ulna is the longer, larger and more medial of the lower arm bones. Many muscles in the arm and forearm attach to the ulna to perform movements of the arm, hand and wrist.

2021年2月28日 · The ulna is a long bone located medially in the forearm. This tutorial reviews the following anatomy: proximal ulna, shaft, and distal ulna.
