Medical terminology

Medical terminology is language used to describe the components, processes, conditions, medical procedures and treatments of the human body.

In the English language, medical terminology generally has a regular morphology; the same prefixes and suffixes are used to add meanings to different roots. The root of a term often refers to an organ, tissue, or condition, and medical roots and affixes are often derived from Ancient Greek or Latin (particularly Neo-Latin). Many medical terms are examples of neoclassical compounds. Historically, all European universities used Latin as the dominant language of instruction and research, as Neo-Latin was the lingua franca of science, medicine, and education in Europe during the early modern period.

Medical terminology includes a large part of anatomical terminology, which includes the anatomical terms of location, motion, muscle, bone, and histology. It also includes language from biology, chemistry, physics, and physiology, as well as vocabulary unique to the field of medicine, such as medical abbreviations. Each branch of medicine has its own clinical and scientific terminology. Medical dictionaries are specialised dictionaries for medical terminology and may be organised alphabetically or according to medical classification systems such as the Systematized Nomenclature of Medicine, International Classification of Diseases, or Unified Medical Language System.
