    Study Notes

    Anatomy

    • Study of the structure and shape of the body and its parts, and their relationships
    • Comes from Greek words meaning "to cut apart"
    • Examines the structure and relationships among body parts
    • Involves separating parts to determine position, relations, and structure
    • Understanding anatomy helps determine functions

    Physiology

    • Study of how the body and its parts function
    • Includes subdivisions like neurophysiology (nervous system) and cardiac physiology (heart)
    • Studies the normal function of the human body (maintaining life)
    • Examines the chemistry and physics of body structures and how they work together

    Relationship between Anatomy and Physiology

    • Structure dictates function
    • Example: Lungs are thin-walled, not muscular, allowing for gas exchange, unlike the muscular heart.

    Divisions of Anatomy

    • Gross Anatomy: Structures visible to the naked eye (muscles, bones, organs)
    • Surface Anatomy: Structures seen on the body's surface
    • Regional Anatomy: Internal structures of a specific body region (e.g., arm)
    • Systemic Anatomy: Structures making up a body system (e.g., cardiovascular system)
    • Microscopic Anatomy: Structures requiring a microscope (cells, tissues)

    Characteristics of Life

    • Organization: Living things are made of cells, organized in a hierarchical manner

    • Responsiveness: Ability to react to changes internally and externally (e.g., sweating in response to heat)

    • Movement: Includes the motion of organs and individual cells.

    • Development and Growth: Changes in structure & function throughout life, including differentiation (cells becoming specialized)

    • Reproduction: Creation of new organisms

    • Metabolism: Breaking down and building up of molecules for energy and growth

    • Growth: Increase in body size.

    • Genes (Heredity): Traits passed from parents to offspring

    • Homeostasis: Maintains internal conditions (balance of fluids and chemicals)

    Levels of Organization

    • Atoms: Simplest building blocks of matter (proton, electron, neutron)
    • Molecules: Formed by combinations of atoms (e.g., water)
    • Cells: The basic functional and structural units of living organisms
    • Tissues: Groups of similar cells working together
    • Organs: Structures composed of two or more tissue types
    • Organ Systems: Groups of organs with related functions
    • Organism: A complete living individual

    Other Details

    • Organelles: Tiny functioning units within cells
    • System: Group of organs that work together
