The radius or radial bone (pl.: radii or radiuses) is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is longer than the radius, but the radius is thicker.
Your radius has a small end where it meets your humerus (upper arm bone), a long shaft in the middle that’s slightly curved and a wider end that meets your wrist. It’s thicker and slightly shorter than your ulna. Even though it’s one long bone, your radius is made up of several parts. These include:
30 Οκτ 2023 · The radius and ulna are long bones that make up the forearm, extending from the elbow to the wrist. In the anatomical position, the radius is found in the lateral forearm, while the ulna is found in the medial forearm.
7 Σεπ 2018 · What is the radial bone facts, where is the radius located in arm, what does it do, anatomy (type, parts, joints formed), labeled diagram and x-ray image.
5 ημέρες πριν · The radius is a long bone in the forearm. It lies laterally and parallel to ulna, the second of the forearm bones. The radius pivots around the ulna to produce movement at the proximal and distal radio-ulnar joints.
2 Ιουλ 2020 · Radius. Radius and ulna are two bones of the forearm. By rotating around the longitudinal axis, the radius is essential for the pronation and supination motions. It has a thicker distal end with a large contact area for the wrist joint.
31 Ιουλ 2023 · Upper-limb malformations include the triphalangeal or absent thumb (s), unequal arm length caused by aplasia or hypoplasia of the radius, or fusion of the carpal and thenar bones. Aplasia or hypoplasia of the radius results in abnormal forearm pronation and supination as well as abnormal wrist adduction and abduction.
