    Study Notes

    Medical Terminology Overview

    • Medical terminology comprises specialized language used in healthcare to describe anatomy, procedures, conditions, and treatments.
    • Terms are constructed using prefixes, root words, combining vowels, and suffixes, allowing precise communication.
    • Example: "Pericarditis" refers to inflammation of the outer heart layer.

    Terminology Essentials

    • Terminology diverges from lexicography; it focuses on specific meanings and concepts rather than general word definitions.
    • Terminology originates from Greek, meaning "all correct," emphasizing clarity in communication.

    Body Planes

    • Coronal (Frontal) Plane: Divides the body into anterior (front) and posterior (back) parts.
    • Sagittal Plane: Divides the body into right and left sections.
    • Transverse (Axial) Plane: Divides body into upper (superior) and lower (inferior) sections.
    • Median Plane: A sagittal plane along the midline, creating equal right and left halves.

    Directional Terms

    • Superior (Cranial): Towards the head or upper part, e.g., hands are in the superior extremity.
    • Inferior (Caudal): Away from the head or lower part, e.g., feet are in the inferior extremity.
    • Anterior (Ventral): Front of the body, e.g., kneecap is on the anterior side.
    • Posterior (Dorsal): Back of the body, e.g., shoulder blades are on the posterior side.
    • Medial: Toward the midline, e.g., middle toe is medial to other toes.

    Levels of Organization in the Body

    • Organization structures range from atoms to the complete organism:
      • Atoms: Smallest chemical unit with a nucleus and electrons.
      • Molecules: Composed of one or more atoms, exhibiting specific physical and chemical properties.
      • Organelles: Specialized structures within cells, such as the nucleus and mitochondria.
      • Cells: The smallest living units, consisting of a membrane, nucleus, and cytoplasm.
      • Tissues: Groups of similar cells functioning together (four types: connective, epithelial, muscle, nervous).
      • Organs: Comprise multiple tissues working together, e.g., heart, lungs, kidneys, brain.
      • Organ Systems: Combinations of organs performing related functions, e.g., muscular, respiratory, and nervous systems.

    Medical Color Prefixes

    • Cyan/o: Blue (e.g., cyanopsia - seeing everything blue).
    • Erythr/o: Red (e.g., erythrocyte - red blood cell).
    • Leuk/o: White (e.g., leukocyte - white blood cell, leukemic - blood condition with excessive white blood cells).
    • Melan/o: Black (e.g., melanoma - a dark tumor).
    • Poli/o: Gray (e.g., poliomyelitis - inflammation of gray matter).
    • Xanth/o: Yellow (e.g., xanthoma - yellow mass or deposit, xanthelasma - yellow plaques around eyes).

    Summary of Medical Terms

    • Colors in prefixes denote specific conditions:
      • Cyan/o for blue,
      • Erythr/o for red,
      • Leuk/o for white,
      • Melan/o for black,
      • Poli/o for gray,
      • Xanth/o for yellow, highlighting the significance of understanding these components in medical terminology.
