Triquetrum is a small bone located in the wrist, also referred to as the triangular fibrocartilage complex. This structure acts as a shock absorber and connects the forearm to the hand, allowing for a range of movement in the wrist joint. While the term 'triquetrum' is well-established in the field of anatomy, other synonyms for this bone include the triquetral bone, the cuneiform bone, and the pyramidal bone. These alternate names are useful for describing the bone to patients or students who may be unfamiliar with the anatomical term 'triquetrum'. It is always important to have a broad vocabulary when discussing anatomy, in order to communicate effectively with others.
