What's in a name? Is an anatomical term only a name?

The purpose of a standard terminology is to facilitate communication. Thus, changing the name of an anatomical structure or the meaning of an anatomical term undermines that aspiration and cuts connections with anatomy's long history. Two types of anatomical terms are the most vulnerable to logical arguments for revision-ones that are descriptive, but viewed, at least by some, as inaccurate, and ones that contain words that are polysemic or vague. A half dozen examples of each type are discussed, including ductus deferens, glandula seminalis, articulationes costochondrales, vulva and fascia. In general, traditional terms should be preserved, but judgments about which terms are traditional should be based on five centuries of modern anatomy, not just the past several decades.
