Origin of Medical Terminology

  • Medical terminology is a consistent and uniform language used by healthcare professionals for effective communication, mainly based on Greek and Latin words.

Basic Elements of Medical Terms

  • Medical terms consist of four basic elements: prefix, root, combining vowel, and suffix.

Word Roots (WR)

  • Word roots are usually derived from Greek or Latin words and frequently indicate a body part.
  • Most medical terms have one or more word roots.

Greek Word Roots

  • Kardia (heart) forms the word root "cardi".
  • Gaster (stomach) forms the word root "gastr".
  • Hepat (liver) forms the word root "hepat".
  • Nephros (kidney) forms the word root "nephr".
  • Osteon (bone) forms the word root "oste".

Combining Forms (CF)

  • Combining forms are word roots plus a vowel, usually "o", and usually indicate a body part.
  • Examples of combining forms include cardi+o, gastr+o, and hepat+o.

    • -centesis, indicating puncture
    • -tomy, indicating incision
    • -ia, indicating a condition
