Corpus: Ulnar carpal collateral ligament

The ulnar carpal collateral ligament runs from the tip of the ulnar styloid process distally. It soon divides into two fiber bundles. One fiber bundle attaches to the medial side of the triquetral bone, while the other attaches to the pisiform bone and the transverse carpal ligament.

Correspondingly, on the lateral side of the wrist, there is the radial carpal collateral ligament.
