    Study Notes

    Module 1 - Foundations of Human Anatomy

    • Anatomy Defined: The study of structure and relationships of parts of an organism. Structure and function are intrinsically linked.
    • Four Areas of Anatomy:
      • Histology (microscopic features)
      • Gross anatomy (macroscopic features)
      • Neuroanatomy
      • Embryology
    • Unity of Form and Function: Structure is instrumental in achieving specific functions; when form is disrupted, dysfunction often results.

    Section 02 - Organization of the Human Body and Anatomical Nomenclature

    • Organization Levels:
      • Chemical level (atoms bonded to form molecules)
      • Cellular level (smallest living structures)
      • Tissue level (cells working together)
      • Organ level (tissues functioning together)
      • Organ system level (related organs working together)
      • Organismal level (all systems working interdependently)
    • Body Regions:
      • Axial region (head, neck, and trunk)
      • Appendicular region (limbs)

    Organ Systems

    • Integumentary: Skin, hair, nails (body covering)
    • Skeletal: Bones and joints (support, movement)
    • Muscular: Muscles (movement, support)
    • Nervous: Brain, spinal cord, nerves (integration/coordination)
    • Endocrine: Glands (hormone production)
    • Digestive: Processing food (from mouth to anus)
    • Respiratory: Breathing (nose, passages, lungs)
    • Cardiovascular: Blood, vessels, heart (transport)
    • Lymphatic: Vessels, cells, structures (immune response)
    • Urinary: Kidneys, ureters, bladder, urethra (waste removal)
    • Reproductive: Sexual maturation and procreation

    Body Cavities

    • Dorsal body cavity: Houses brain (cranial cavity) and spinal cord (vertebral cavity)
    • Ventral body cavity: Contains structures anterior to the vertebral column
      • Thoracic cavity (superior to diaphragm) - contains heart and lungs
        • Mediastinum contains esophagus and trachea
      • Abdominal-pelvic cavity (inferior to diaphragm) - contains digestive organs and reproductive organs

    Section 03 - Basic Tissue (Epithelium)

    • Epithelial tissue: Made of tightly packed cells with little extracellular material.
    • Types: Covering epithelium (lines surfaces), glandular epithelium (secretory)
    • Characteristics:
      • Cellularity (cells joined by junctions)
      • Polarity (apical and basal surfaces)
      • Attachment (basal lamina)
      • Avascularity (nourishment from surrounding tissues)
      • Regeneration (high capacity to repair)
    • Classifications:
      • Simple: One layer of cells (squamous, cuboidal, columnar)
      • Stratified: Multiple layers of cells (squamous, cuboidal, columnar, transitional)
    • Functions: Protection, secretion, absorption, excretion, filtration, diffusion.

    Section 04 - Connective Tissue

    • Connective tissue: Diverse, abundant, with cells embedded in an extracellular matrix.
    • Components:
      • Cells (fixed, wandering)
      • Fibers (collagen, elastic, reticular)
      • Ground substance (fluid)
    • Types:
      • Connective tissue proper (loose, dense)
      • Supporting connective tissue (cartilage, bone.
      • Fluid connective tissue (blood, lymph)

    Connective Tissue subtypes and functions discussed in detail

    • Loose connective tissue (e.g., adipose): Cushioning and insulation, cushioning organs
    • Dense connective tissue (e.g., tendons, ligaments): Strength and support providing structural scaffolding to organs and tissues
    • Cartilage (hyaline, elastic, fibrocartilage): Support and flexibility (e.g., nose, ears, intervertebral discs)
    • Bone: Support and protection, mineral storage, blood cell production
