  1. what is anatomy?
    • -study of structure (at different levels of organization) and the relationships among structures.
    • -study of internal and external structures of the body and the physical relationships among body parts


    • Subdivisions
    • include: surface, gross, systemic, regional, radiographic, developmental,
    • embryology, cytology, pathological

    Ex. How a muscle attaches to the skeleton
  2. What is Physiology?
    • -study of how body structures function.
    • -study of how living organisms perform their vital functions

    Subdivisions include: cell, system, exercise, pathophysiology, neurophysiology, renal,

    endocrinology, respiratory, immunophysiology, cardiovascular, reproductive.

    • Example:
    • How a muscle contracts or the forces that cause contracting
  3. What are the Levels of Organization?
    • Chemical – atoms
    • Cell– structural & functional unit

    • Tissue– group of cells with similar function
    • Organ– 2 or more tissues performing function

    • System– related organs with common function
    • Organism
