The coracobrachialis muscle: typical morphology, accessory forms, and the issues with terminology

In conclusion, it is of paramount importance to adopt common-universal terminology. Hence, considering recent findings, if the CB origin and/ or the insertion differs from the typical anatomy, an “atypical CB” is the proper definition of the muscle, while if this “atypical CB” coexists with a typical CB, the terminology “accessory CB” may be used.
