What ligament connects the radius and ulna?

What ligament connects the radius and ulna?

Annular & quadrate ligaments: These ligaments secure the radius bone firmly against the ulna.

Which ligament holds the ulnar in place?

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 ligament that joins the point between the distal ends of the radius and ulna?

The distal radioulnar articulation is composed of the palmar radioulnar ligament (volar radioulnar ligament) that attaches the anterior radius to the anterior ulna, the dorsal radioulnar ligament (posterior radioulnar ligament) which attaches the posterior radius to the posterior ulna, and the articular disc which lies …

What ligaments are attached to the radius?

The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna. Per Terminologia Anatomica, the spelling is “anular”, but the spelling “annular” is frequently encountered.

What is the name of the process at the proximal end of the ulna?

The ulna is a long thin bone with a small distal head that bears the styloid process, and an expanded proximal end. The proximal end terminates in the olecranon process and bears the semilunar notch on its upper surface. In man, the head of the ulna does not articulate with any of the bones of the carpus.

How does the humerus articulate with the radius and ulna?

Distally, the humerus flattens to articulate with the ulna and radius at the elbow joint. The medially located trochlea articulates with the ulna. Located laterally to this is the capitulum that articulates with the radius.

Where is the proximal radius?

The radius is one of the long bones of the forearm that extends from the wrist to the elbow. The proximal radius is the disc- shaped part of this bone that is near the elbow. This shape is what allows us to turn our forearm from a palms-up position to a palms-down position.

What is the radius and ulna?

The radius and the ulna constitute as the bones of the forearm. The antebrachial region, as it is clinically known, spans the length of the region which extends roughly from elbow to wrist. The radius is the lateral of the two bones, which makes the ulna the medial bone of the forearm.

What is the proximal end of ulna and radius?

Its proximal end consists of the following processes (2) and notches (2): Olecranon: A hook-shaped process, located on the posterior aspect of the proximal ulnar end, Trochlear notch: A C-shaped notch, located anterior to the olecranon. It articulates with the trochlea of the humerus at the elbow joint.

Is the ulna lateral to the radius?

The radius is the thicker and shorter of the two long bones in the forearm. It is located on the lateral side of the forearm parallel to the ulna (in anatomical position with arms hanging at the sides of the body, palms facing forward) between the thumb and the elbow.
