    Study Notes

    Anatomy

    • Definition: Study of the structure of the body and its parts.
    • Types:
      • Gross Anatomy: Study of structures visible to the naked eye (e.g., organs).
      • Microscopic Anatomy: Study of structures at the cellular level (e.g., histology).
      • Developmental Anatomy: Study of anatomical changes throughout life stages.

    Physiology

    • Definition: Study of the function of body parts and systems.
    • Levels of Organization:
      • Cellular Level: Cell functions like metabolism and transport.
      • Tissue Level: Group of cells with a common function (e.g., epithelial, muscle).
      • Organ Level: Composed of different tissues to perform specific functions (e.g., heart).
      • System Level: Group of organs that work together (e.g., cardiovascular system).

    Key Systems

    1. Skeletal System:

      • Composed of bones and cartilage.
      • Functions: Support, movement, protection, blood cell production.

    2. Muscular System:

      • Composed of skeletal, smooth, and cardiac muscles.
      • Functions: Movement, posture, heat production.

    3. Circulatory System:

      • Includes heart, blood, and blood vessels.
      • Functions: Transport nutrients, oxygen, hormones; remove waste.

    4. Nervous System:

      • Composed of the brain, spinal cord, and nerves.
      • Functions: Control and communicate between body parts.

    5. Respiratory System:

      • Includes nose, trachea, lungs.
      • Functions: Gas exchange (oxygen and carbon dioxide).

    6. Digestive System:

      • Composed of gastrointestinal tract and accessory organs (e.g., liver).
      • Functions: Break down food, absorb nutrients, eliminate waste.

    7. Endocrine System:

      • Comprises glands that secrete hormones (e.g., thyroid, adrenals).
      • Functions: Regulate metabolism, growth, reproduction.

    8. Immune System:

      • Includes lymph nodes, spleen, white blood cells.
      • Functions: Defend against pathogens, remove damaged cells.

    9. Integumentary System:

      • Consists of skin, hair, nails.
      • Functions: Protect underlying tissues, regulate temperature, sensory perception.

    10. Reproductive System:

      • Male and female reproductive organs (e.g., testes, ovaries).
      • Functions: Produce gametes, facilitate reproduction.

    Homeostasis

    • Definition: Maintenance of a stable internal environment.
    • Mechanisms:
      • Feedback Mechanisms:
        • Negative Feedback: Reduces output to maintain equilibrium (e.g., temperature regulation).
        • Positive Feedback: Enhances output for specific processes (e.g., childbirth).

    Important Concepts

    • Anatomical Position: Standard body position used as a reference (standing, facing forward, arms at sides).
    • Directional Terms:
      • Superior/Inferior: Above/Below
      • Anterior/Posterior: Front/Back
      • Medial/Lateral: Closer to the midline/Further from the midline
      • Proximal/Distal: Closer to point of attachment/Further from point of attachment

    Cells

    • Basic Unit of Life: All living organisms composed of cells.
    • Types:
      • Prokaryotic: Simple, no nucleus (e.g., bacteria).
      • Eukaryotic: Complex, with nucleus (e.g., plant and animal cells).

    Tissues

    • Types:
      • Epithelial: Covers surfaces, lines cavities.
      • Connective: Supports and binds other tissues (e.g., bone, blood).
      • Muscle: Responsible for movement.
      • Nervous: Transmits impulses for communication.
