What articulates to the head of the radius?

The radius articulates proximally at the elbow with the capitulum of the humerus and the radial notch of the ulna. It articulates at its distal end with the ulna at the ulnar notch and with the articular surfaces of the scaphoid and lunate carpal bones.

Which bone structure articulates with the radial head?

The radial head articulates with the capitellum of the distal humerus and the ulna (proximal radial ulnar joint).

What structure of the arm bone articulates with the head of the radius?

The capitulum articulates with the radius bone of the forearm. Just above these bony areas are two small depressions.

What structure articulates with the olecranon?

The most proximal aspect of the olecranon articulates with the olecranon fossa of the distal humerus posteriorly and the coronoid process articulates with the coronoid fossa of the humerus anteriorly.

What does the trochlea articulate with?

The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.

What type of articulation forms between the head of the radius and the capitulum of the humerus in the elbow joint?

synovial hinge joint
the radius and ulna. The elbow: The elbow joint is a synovial hinge joint with two articulations. The trochlea of the humerus articulates with the trochlear notch of the ulna, and the capitulum of the humerus articulates with the head of the radius.

Which fossa on the humerus articulates with the head of the radius?

coronoid fossa
The projection that forms the lower border of the trochlear notch, the coronoid process, enters the coronoid fossa of the humerus when the elbow is flexed. On the outer side is the radial notch, which articulates with the head of the radius. The head of the bone is elsewhere roughened for muscle attachment.

What structure and bone articulates with the trochlea of the humerus?

The upper end of the ulna presents a large C-shaped notch—the semilunar, or trochlear, notch—which articulates with the trochlea of the humerus (upper arm bone) to form the elbow joint.

What articulates with the Trochlea?

Which term refers to the articulation between the distal and proximal ends of the radius and ulna?

The elbow joint is composed of the distal end of the humerus and the proximal ends of the radius and the ulna (see the images below).

Where are the articulations of the radius located?

The radius articulates in four places: Elbow joint – Partly formed by an articulation between the head of the radius, and the capitulum of the humerus. Proximal radioulnar joint – An articulation between the radial head, and the radial notch of the ulna. Wrist joint – An articulation between the distal end of the radius and the carpal bones.

What does the head of the radius look like?

The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus. The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent,…

Which is part of the elbow forms the articulation?

Elbow joint – Partly formed by an articulation between the head of the radius, and the capitulum of the humerus. Proximal radioulnar joint – An articulation between the radial head, and the radial notch of the ulna.

What is the shape of the radius of the humerus?

The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.
