What is the humeroradial joint?
What is the humeroradial joint?
The humeroradial joint is the part of the elbow joint where the capitulum of the humerus articulates with the fovea on the head of the radius.
What type of joint is Radiocapitellar?
Radiocapitellar joint – This joint, which is between the radial head and the lateral condyle of the humerus, is less constrained and allows both flexion and extension and forearm rotation.
What kind of synovial joint is the humeroradial joint?
The humeroradial joint is the joint between the head of the radius and the capitulum of the humerus, is a limited ball-and-socket joint, hinge type of synovial joint.
What kind of joint is the Radiohumeral?
Radiohumeral Joint: As the secondary hinge of the elbow, the radiohumeral joint aids in the same flexion and extension movements facilitated by the humeroulnar joint. It extends from the head of the radius to the capitulum of the humerus.
How do you remember capitulum and Trochlea?
The mnemonic of the order of appearance of the individual ossification centers is C-R-I-T-O-E: Capitellum, Radial head, Internal (medial) epicondyle, Trochlea, Olecranon, External (lateral) epicondyle.
What is Radiocarpal?
The radiocarpal joint is a synovial joint formed by the articulation between the distal radius and the scaphoid, lunate, and triquetrum as well as the soft tissue structures that hold the joint together.
What is Capitellum?
The capitellum, also referred to as the capitulum, is the lateral part of the humeral condyle that articulates with the radial head.
What does the Radiohumeral joint do?
Radiohumeral joint is where movement between the radius and humerus occurs. Proximal radioulnar joint is where movement between the radius and ulna occurs.
What does the capitulum articulate with?
The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.
Is the trochlea proximal or distal?
Humerus (Figure 3) — The distal end of the humerus has a unique set of bony features that articulate with the radius and ulna. The trochlea is the roughly hourglass-shaped feature on the distal end of the humerus.
Where does the capitulum of the humerus articulate?
The humeroradial joint is the part of the elbow joint where the capitulum of the humerus articulates with the fovea on the head of the radius.

What is the definition of the word humerus?
Relating to or characterizing the humerus and the radius, especially the ratio of the length of one to the length of the other. The Dictionary added new words and definition to our vast collection, and we want to see how well-versed you are in the formally recognized new lingo. Take the quiz! What does JEDI stand for?
Where does the extension of the humeroulnar joint come from?
Extension in the humeroulnar joint is produced by the triceps brachii and anconeus muscle, with a tiny contribution from the muscles arising from the lateral epicondyle of the humerus, such as the extensor digitorum muscle . This article incorporates text in the public domain from page 321 of the 20th edition of Gray’s Anatomy (1918)
What is the articulation of the proximal radioulnar joint?
The proximal radioulnar joint is the articulation between the circumferential head of the radius and a fibro-osseous ring formed by the radial groove of the ulna and the annular ligament that hold the head of the radius in this groove.
