1. Function of Epithelial tissue
    • Physical Protection for exposed and internal surfaces from dehydration, abrasion, and physical, chemical and biological agents
    • Slective permeability - regulates the passage of certain molecules in or out of a certain region of the body.
    • Secretion - some epithelial cells called exocrine cells produce secretions such as sweat or oil.
    • Sensations - possess nerve endings that can detect light, taste, sound, smell and hearing.
  2. Connective Tissue Function
    • Physical Protection
    • Support & Structural framework
    • Binding of structures
    • Storage
    • Transport
    • Immune Protection
  3. Muscle Tissue Function
    Facilitates movement of skeleton or organ walls
  4. Nervous Tissue Function
    Neurons: Control Activities, process information

    Glial Cells: Support and protect neurons
  5. Types of Intercellular Junctions
    • Tight Junctions
    • Adhering Junctions
    • Desmosomes
    • Gap Junctions
  6. Tight Junctions
    • Relays information to other cells.
    • Prevent passage of molecules and ions through the space between cells, so they must pass through the cell (by diffusion or active transport).

    Example: Muscle Memory
  7. Adhering Junctions
    • Provide strong mechanical attachments between adjacent cells.
    • Hold cardiac muscle cells tightly together as the heart expands and contracts
    • Hold epithelial cells together
    • responsible for contact inhibition
  8. Gap Junctions
    • Permit free passage between the cells of ions and small molecules.
    • Permit change in membrane potential to pass from cell to cell.
  9. Desmosomes
    localized patches that hold two cells tightly together.
  10. Characteristics of Epithelial Tissue
    • Cellularity
    • Polarity
    • Attachment
    • Avascularity
    • Innervention
