    Study Notes

    Introduction to Anatomy

    • Anatomy is the study of internal and external structures of the body and their relationships.
    • Key examples of relationships include the connection between bones and muscles.
    • Anatomy is divided into two main subdivisions:
      • Microanatomy: requires a microscope for study; includes cytology (study of cells) and histology (study of tissues).
      • Gross Anatomy: focuses on structures visible to the naked eye, such as bones, heart, and stomach; includes the study of body cavities (cranial, thoracic, abdominopelvic).

    Levels of Organization

    • Organization of biological systems progresses from simple to complex structures:
      • Chemical Level:

        • Composed of atoms, like Hydrogen (H) and Oxygen (O).
        • Atoms combine to form molecules, for example, H2O (water).
      • Cellular Level:

        • Molecules form organelles which in turn make up cells.
        • Cells are the fundamental units of structure and function; differences exist among cell types like erythrocytes (red blood cells), neurons, and muscle cells.
      • Tissue Level:

        • Comprised of groups of structurally similar cells that carry out a common function.
        • Four major types of tissues exist: epithelial, connective, muscle, and nervous tissues.
      • Organ Level:

        • Consists of two or more tissues working together for a shared function.
        • Example: the stomach, which includes all four tissue types and is involved in digestion.
      • Organ System Level:

        • Involves several related organs functioning together to fulfill specific purposes, such as the respiratory system which includes the lungs and trachea, working to facilitate respiration.
      • Organism Level:

        • Represents the complete entity; all systems collectively function to sustain life.

    Hierarchical Structure

    • This organization is hierarchical, with each level encompassing the structures below it.
