Radial bone (radius) on the proximal end has a head of radius (caput radii) with a flat indentation - articular fovea (fovea articularis) for articulation with the head of the condyle of the humerus. The periphery of the head is occupied by the articular circumference (circumferentia articularis), which articulates with the radial incision of the ulna. The area of the bone below the head is the neck of the radius (collum radii). Below the cervix on the anterior medial side of the bone is the tuberosity of the radius (tuberositas radii) - the attachment point of the biceps tendon of the shoulder. On the distal end of the radius, from its medial side, there is an ulnar incision (incisura ulnaris), with which the head of the ulna connects. From the lateral side of the bone, the styloid process (styloidideus processus) departs from below. At the distal end of the radius there is a concave carpal articular surface (facies articularis carpea) for articulation with two carpal bones (navicular and semilunar). On the rear surface of the well visible grooves, which adhere to the tendons of the muscles.
