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.
