  1. What is the structure of medical words?
    • Most medical words are composed of 2 or more terms. To define a medical word:
    • -divide the word into its terms
    • -analyze the terms
    • -define the word
  2. Examples of Medical Terminology Examples:
    • -pericarditis-
    • -peri=around; card=heart; itis=inflammation (Inflammation around the heart)

    • -Oncology-
    • -onco=tumor, mass; logy=study of (Study of Tumors)
  3. How many categories of terms are there?
    5 categories of terms
  4. Term + Term (.....+.....) =medical word
    • There are 5 categories of terms:
    • 1.Prefix-beginning of a word---(ex. Pre___; post____). Designated by a "___" after the term.
    • 2.Suffix- edning of a word. --(ex. ___stomy; ___itis)--Designated by a "___" before the term.
    • 3.Root- foundations/base of a word (ex. hepat; gastr).
    • 4.Combining vowel-vowel (usually "o") added to a root (ex. gastro)
    • Use a combining vowel when joining:
    • a.root to another root (ex. gastrohepatitis)
    • b.root to a suffix beginning with a consonant (ex. cadiomegaly)
    • 5.Combining form - root +vowel (ex. hepat/o; gastr/o)
  5. 5.Combining form - root +vowel (ex. hepat/o; gastr/o)
    Designated by a "/" between the root and the vowel.
    • Examples 1:
    • Hyperleukocytosis:
    • Hyper-(prefix)=excessive
    • leuko-(combing form)=white
    • cyt-(root)=cell
    • osis-(suffix)=condition of
    • Definition: Condition of excessive white blood cells (leukocytes)
  6. 5.Combining form - root +vowel (ex. hepat/o; gastr/o)
    Designated by a "/" between the root and the vowel.
    • Example 2:
    • Hematotoxic:
    • Hemato-(combining form)=blood
    • tox-(root)=poison
    • ic-(suffix)=pertaining to
    • Definition: Pertaining to blook poisoning
  7. Tips:
    Some terms have more than one definition. To determine the correct definition in a particular medical word, analyze the other terms in the word.
    • Example:
    • Poliomyelitis:
    • polio=gray (matter)
    • myel=spinal cord, bone marrow
    • itis=inflammation
    • Definition: Inflammation of the gray matter of the spinal cord. The bone marrow does not have gray matter.
  8. Tips 2:
    Some terms may function as a root/combining form in one word and a suffix in anotherr word. Classification depends upon the specific medical word.
    • Example:
    • Cytology:
    • Cyto-(combining form)=cell
    • logy-(suffix)=sudy of
    • Definition: Study of cells

    • Example 2:
    • Erythrocyte:
