    Study Notes

    Medical Terminology Introduction

    • Medical terminology is based on anatomical and physiological language.
    • Terminologia Anatomica standardizes terms for body parts.
    • Eponyms are terms derived from people's names (discoverers, describers, inventors).

    Word Parts

    • Word etymology studies word origins and evolution.
    • Medical terms use four word parts: word root, combining form, suffix, and prefix.

    Word Root

    • Contains the basic meaning, often indicating the body part involved.
    • Example: Stomach

    Combining Form

    • Word root plus a combining vowel (used when a consonant-starting suffix is added).
    • Example: Stomach

    Suffix

    • Usually indicates procedure, condition, disorder, or disease.
    • Always at the word's end.
    • Example: Inflammation

    Prefix

    • Often indicates location, time, number, or status.
    • Always at the word's beginning.
    • Example: Increased or Excessive

    Word Part Guidelines

    • A word root cannot stand alone.
    • A suffix must be added to complete the term.
    • Combining vowels are used when a suffix beginning with a consonant is added to a word root.
    • Prefixes are always placed at the beginning of the word.

    Word Roots and Combining Forms Indicating Color

    • Cyan/Cyan-: Blue; Example: Cyanosis (blue discoloration of skin due to oxygen lack).
    • Erythr/Erythro-: Red; Example: Erythrocyte (mature red blood cell).
    • Leuk/Leuko-: White; Example: Leukocyte (white blood cell).
    • Melan/Melano-: Black; Example: Melanosis (unusual black pigment deposits).
    • Poli/Polio-: Gray; Example: Poliomyelitis (viral infection of spinal cord's gray matter).

    Combining Forms and Vowels

    • When joining two word roots, a combining vowel is always added to the first.
    • A combining vowel is used with the second word root only if the suffix starts with a consonant.
    • Example: Gastroenteritis (inflammation of the stomach and small intestine).

    Suffixes

    • A combining vowel is used if the suffix begins with a consonant (e.g., Neuroplasty, Neurorrhaphy).
    • No combining vowel is used if the suffix begins with a vowel (e.g., Tonsillitis, Tonsillectomy).

    Suffixes as Noun Endings

    • Suffixes like -a, -um, -y, -e, -us change word roots into nouns.
    • Example: Cranium

    Suffixes Meaning "Pertaining To"

    • Suffixes like -ac, -al, -an, -ar, -ary, -eal, -ical, -iar, -ic, -ine, -ior, -ory, -ous, -tic change word roots into adjectives.
    • Example: Cardiac

    Suffixes Meaning "Abnormal Condition"

    • Suffixes like -ago, -iasis, -osis, -esis, -ion, -ory, -ia, -ism, -ous indicate abnormal conditions or diseases.
    • Example: Gastrosis
    • -algia or -dynia: Pain; Examples: Gastralgia, Gastrodynia
    • -itis: Inflammation; Example: Gastritis
    • -megaly: Enlargement; Example: Hepatomegaly
    • -malacia: Abnormal softening; Example: Arteriomalacia
    • -necrosis: Tissue death; Example: Arterionecrosis
    • -sclerosis: Abnormal hardening; Example: Arteriosclerosis
    • -stenosis: Abnormal narrowing; Example: Arteriostenosis
    • -centesis: Surgical puncture (e.g., Abdominocentesis)
    • -graphy: Process of producing a picture or record (e.g., Angiography)
    • -gram: Picture or record (e.g., Angiogram)
    • -plasty: Surgical repair (e.g., Myoplasty)
    • -scopy: Visual examination (e.g., Arthroscopy)

    "Double R" Suffixes

    • -rrhage or -rrhagia: Bleeding (e.g., Hemorrhage)
    • -rrhaphy: Surgical suturing (e.g., Myorrhaphy)
    • -rrhea: Flow or discharge (e.g., Diarrhea)
    • -rrhexis: Rupture (e.g., Myorrhexis)

    Prefixes

    • Prenatal: Before birth
    • Perinatal: Surrounding birth
    • Postnatal: After birth

    Prefixes Describing Direction, Quantity, Size, and Amount

    • The lecture mentions these prefixes but doesn't list specific examples.

    Contrasting Prefixes

    • The lecture mentions contrasting prefixes but doesn't provide examples.
