What forms the humeroradial joint?
The humeroulnar joint is formed between the humerus and ulna and allows flexion and extension of the arm. The humeroradial joint is formed between the radius and humerus and allows movements like flexion, extension, supination, and pronation.
What does humeroulnar joint do?
The humeroulnar joint, is part of the elbow-joint or the Olecron Joint, between the ulna and humerus bones is the simple hinge-joint, which allows for movements of flexion, extension and circumduction. The Humero-Ulnar Joint is the junction of trochlear notch of the ulna and the trochlea of the humerus.
How many ligaments are in the elbow joint?

Is there a humeroradial joint?
Humeroradial joint is the joint between the capitulum on the lateral aspect of the distal end of the humerus with the head of the radius.
Which joint do the humeroradial joint and the humeroulnar joint form?
The humeroulnar and humeroradial articulations of the elbow joint are served by the musculocutaneous, radial, and ulnar nerves.
Is the humeroulnar joint a hinge joint?
The humeroulnar joint is a simple hinge, whereas the humeroradial joint is a pivot joint resembling a ball-and-socket joint. The proximal and distal radioulnar joints are mirror images, allowing the radius to spin during pronation and supination.
Where are the ligaments in the elbow?
The ulnar collateral ligament complex is located on the inside of the elbow (pinky or medial side). It is attached on one side to the humerus (the bone of the upper arm) and on the other side to the ulna (a bone in the forearm).
What are the main ligaments that hold the elbow together?
There are four main ligaments in the elbow.
- Medial collateral ligament. Located on the inside of the elbow this ligament connects the ulna to the humerus.
- Lateral collateral ligament. Located on the outside of the elbow this ligament connects the radius to the humerus.
- Annular ligament.
- Quadrate ligament.
What are Intercarpal joints?
The intercarpal joints are the synovial plane joints that connect the carpal bones. They gather three sets of joints; Joints of the proximal carpal row, that connect the adjacent surfaces of the scaphoid, lunate and triquetrum bones.
Is humeroradial joint ball-and-socket?
