The ulna is one of two bones that give structure to the forearm. The ulna is located on the opposite side of the forearm from the thumb. It joins with the humerus on its larger end to make the elbow joint, and joins with the carpal bones of the hand at its smaller end.
Then, what is the end of the ulna called?
The ulna extends through the forearm from the elbow to the wrist, narrowing significantly towards its distal end. At its proximal end it forms the elbow joint with the humerus of the upper arm and the radius of the forearm. The ulna extends past the humerus to form the tip of the elbow, known as the olecranon.
What does the ulna bone look like?
Structure. The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist.
Which is radius and ulna?
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 does a broken ulna feel like?
A broken forearm usually causes immediate pain. Because both bones are usually involved, forearm fractures often cause an obvious deformity — your forearm may appear bent and shorter than your other arm. Inability to rotate arm. Numbness or weakness in the fingers or wrist (rare)
