Ulnar Collateral Ligament

We just learned about the Humeroradial Ligaments or RCL that connects the upper arm called the humerus to one of the forearm bones called the radius.

Another bunch of connective tissue connects the humerus to the other forearm bone called the ulna.
This is the Ulnar Collateral Ligament, sometimes just called the UCL.

Just like the RCL, the UCL helps hold the elbow joint together when you move your arm around.
