The Part of the Arm Opposite the Elbow
The part of the arm opposite the elbow is known as the forearm. The forearm is made up of two long bones, the radius and ulna, which are connected by a network of muscles, tendons, and ligaments. It is responsible for many of the movements of the hand and wrist.
Bones in the Forearm
The radius is located on the thumb side of the arm and runs parallel to the ulna. The ulna is located on the pinky side of the arm and runs parallel to the radius. Both bones are connected at their proximal ends (closest to the elbow) by a joint called the radioulnar joint. This joint allows for rotation of the forearm.
Muscles in the Forearm
The muscles in the forearm are responsible for flexing and extending your wrist and fingers. These muscles include: brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, flexor carpi radialis, palmaris longus, flexor digitorum superficialis, flexor digitorum profundus, pronator teres, supinator, and abductor pollicis longus.
