Ulnar collateral ligament

Definition

The ulnar collateral ligament is a band of tough, fibrous tissue that connects the humerus (upper arm bone) to the ulna (one of the forearm bones) at the elbow joint, providing stability. It plays a crucial role in preventing the elbow from bending too far away from the body.
