    Study Notes

    Anatomy and Physiology Fundamentals

    • Importance of learning "normal" anatomy and physiology for understanding body functions.
    • Anatomical position: standard reference for body orientation, important for consistent communication.
    • Distinction between simple glands (single duct) and compound glands (multiple ducts).

    Chapter 1: Physiology and Anatomy

    • Characteristics of life: includes organization, responsiveness, growth, differentiation, reproduction, movement, metabolism, and excretion.
    • Types of anatomy:
      • Gross Anatomy: studies visible structures.
      • Microscopic Anatomy: includes cytology (cells) and histology (tissues).
    • Types of physiology: explores functioning at cell, organ, and systemic levels.

    Chapter 2: Chemistry Basics

    • Atoms consist of electrons, protons, and neutrons which determine their chemical behavior.
    • Understanding molecular attraction and common element symbols is crucial.
    • Types of chemical bonds:
      • Ionic Bonds: transfer of electrons.
      • Covalent Bonds: sharing of electrons.
      • Hydrogen Bonds: weak attractions between polar molecules.
    • Reactions include decomposition, synthesis, reversible reactions, and hydrolysis.
    • Buffers maintain pH balance in biological systems.

    Levels of Organization of the Body

    • Hierarchical structure from chemical level to organism.
    • Homeostasis: maintaining internal stability through mechanisms of negative and positive feedback.

    Chapter 3: Water and Organic Molecules

    • Four properties of water: solubility, solution, solvent, solute.
    • Importance of ATP in energy transfer; ATPases are catalysts that convert it.
    • Four organic molecules: focus on composition, cell membrane crossing ability, and carbohydrate naming conventions.
    • pH scale: measurement of hydrogen ion concentration with neutral (7), acid (lower), and base (higher) readings.

    Cell Membrane and Transport

    • Cell membrane structure and function adaptations: microvilli increase surface area, cilia assist in movement.
    • Active transport requires energy (ATP), contrasting with passive transport mechanisms.
    • Mitosis vs. meiosis: key differences in cell division processes.
    • Osmosis: movement of water across membranes in response to concentration gradients.

    Chapter 4: Tissue Types

    • Four basic tissue types: epithelial, connective, muscle, and nervous tissue, each with distinct functions.
    • Cell adhesion through structures like tight junctions and gap junctions ensures integrity.
    • Gland types:
      • Endocrine (hormonal) versus exocrine (secretory).
      • Gland secretion methods: holocrine, merocrine, apocrine.
    • Connective tissue characteristics: strong vs. flexible fibers, categorized as dense, loose, or specialized.

    Laboratory Skills

    • Familiarity with directional terms (e.g., proximal vs. distal, superior vs. inferior).
    • Body cavities and organ identification, including recognizing retroperitoneal organs.
    • Understanding of serous membranes and mucous membranes in body functions.
    • Knowledge of tissue identification: simple squamous, stratified squamous, simple cuboidal, and various epithelial types.
