The terms used in the practice of health care, particularly medical terms are often ancient in origin and confusing for lay people as well as other clinicians. Many terms fall out of use over time as more is known about the etiology of a condition or as new treatments become available. The terms in the listings that lie within this category are not necessarily correct for today's use and are retained for historical purposes only.
This is a developmental work. The terms are constantly being revised, added to or made more accurate. Please submit any terms you would like to see included or advise the editor of any details you believe could be more correctly expressed.
