The ulnar notch is on the radius and the radial notch is on the ulna. Pointy shit on the end of the radius. Where ulna fits in.

The radius is the lateral of the two bones which makes the ulna the medial bone of the forearm. Its concave superior surface articulates with the capitulum of the humerus and its cylindrical lateral surface articulates with the radial notch of the ulna. This notch allows for the radius to move smoothly and freely on the ulna which allows for the rotation of the forearm.

Anatomy - Ulna and Radius - Easy to understand- Anatomy 101 Monday - YouTube. Radial Headcaput radii is a proximal disc-shaped prominence. The rotational anatomy of the radius and ulna varies significantly between individuals but is similar in contralateral limbs.

Dont get those confused. It articulates forms a joint with the radius at the ulnar notch but does not articulate directly with the wrist bones. The ulna is a long bone in the forearm.

The radius bone os radius supports the lateral thumb side of the forearm and the ulna bone os ulna supports the medial little finger side. Clinical relevance Distal radius volar cortex rotational anatomy can help guide treatment of DR fractures and malunions as well as assist in positioning of wrist arthroplasty implants particularly in the presence of bone loss. The radius and the ulna constitute as the bones of the forearm.

The bones of forearm region are radius and ulna which are attached to each other by an interosseous ligament. As its name suggests the radial notch is the point where the radius joins the ulna. It is known as the oblique cord or the oblique ligament and its fibers run in the opposite direction of the interosseous ligament.

The radius and ulna are connected by a sheet of thick fibrous tissue called the interosseous ligament or the interosseous membrane. The ulna though placed higher than the radius is partially developed. This thin connective tissue membrane divides the forearm into anterior and posterior compartments.

Indention on the end of the radius. It lies medially and parallel to the radius the second of the forearm bones. Cup part of the radius.

The radius is bigger than ulna and is fully developed. The ulna acts as the stabilising bone with the radius pivoting to produce movement. The rotational anatomy of the radius and ulna varies significantly between individuals but is similar in contralateral limbs.

This videos gives you a preview to our full length tutorial on the bones of the forearm the radius and ulna. The radius and ulna are the bones of the forearm. The radius bone os radius supports the lateral thumb side of the forearm and the ulna bone os ulna.

Head of Ulna Unlike the radius the head of the ulna is located at the distal end. A smaller ligament connects the proximal ends of the radius and ulna.
