30 Οκτ 2023 · The radial musculature consists of three muscles located at the lateral forearm. They all run from or near the lateral epicondyle of the humerus to the wrist. As their bellies and tendons lie superficially, they can be easily palpated. Contents. Anatomy and supply. Brachioradialis muscle. Extensor carpi radialis longus.
28 Νοε 2023 · Overview of the bones that define the forearm, the radius and ulna. Extending from the wrist to the elbow joint is the region of the upper extremity called the forearm (antebrachium). The forearm helps the shoulder and the arm in force application and the precise placement of the hand in space, with the help of the elbow and radioulnar joints.
30 Οκτ 2023 · The radius is the lateral bone of the forearm. It is a long bone that has three main parts: a proximal end, shaft and a distal end. The proximal end has a head which articulates with both the distal humerus and the proximal ulna, while the distal end articulates with the head of the ulna and carpal bones at the wrist.
The anatomical term for the forearm is the antebrachium. Two long bones, the radius and ulna, structure this section of the arm, also acting as the point of attachment for several muscles originating in this area.
The radius and the ulna are long, slightly curved bones that lie parallel from the elbow, where they articulate with the humerus, to the wrist, where they articulate with the carpals. The radius is located laterally, near the thumb, and the ulna medially, near the little finger.
The radial nerve innervates the anconeus, brachioradialis, and extensor carpi radialis longus forearm muscles. In the radial tunnel, at the level of the radiocapitellar joint, the nerve divides into two branches: the deep (motor) radial nerve and the superficial (sensory) radial nerve.
6 Ιουν 2023 · The radius is the thicker and shorter of the two long bones in the forearm. It is located on the lateral side of the forearm parallel to the ulna (in anatomical position with arms hanging at the sides of the body, palms facing forward) between the thumb and the elbow. The radius and ulna pivot around one another to allow rotation of the wrist.
