Ask a question


The forearm is the part of the upper limbs situated between the elbow joint and the wrist joint. It is composed of only two bones, the radius and the ulna, or cubitus, which allow a movement of rotation, one around the other. The radius favors the wrist joint, and the ulna favors the elbow joint. There are 19 muscles in the forearm. They allow the movements of the wrist, the fingers, and the forearm. The radial and ulnar arteries pass through the forearm.
