  1. the smallest living unit of organization in the body
    the cell
  2. kicking something out of the cell (i.e. ameloblasts leaving a slimy train)
    exocytosis
  3. bringing something into the cell (i.e. ameloblasts leaving a slimy trail)
    endocytosis
  4. a form of endocytosis. the cell eats whatever it brings in.
    Phagocytosis
  5. cells work together to form___________. Tissues work together to form___________. Organs work together to form_______________.
    give an example.
    • tissues
    • organs
    • systems
    • heart cell - heart tissue - heart - circulatory system
  6. keeps good things in and bad things out
    cell membrane
  7. the fluid contained within the cell membrane
    cytoplasm
  8. specialized structures within the cell
    organelles
  9. the brain of the cell where the DNA is kept
    organelle; nucleus
  10. the power source that creates Adenosine Triphosphate (ATP)
    organelle; mitochondria
  11. the protein factory of the cell
    organelle; Ribosomes
  12. modify, store, segregate, and transport proteins
    organelle; endoplasmic reticulum
  13. segregation, packaging, and transportation of proteins
    organelle; golgi complex
  14. digestion in cell
    organelle; lysosome
  15. help with cell division
    organelle; centrosome
  16. specialized proteins that help keep the cell's shape - protein filaments give it shape and help connect it to other cells
    cytoskeleton
  17. interstitial fluid. Comes from the blood stream. Provides a medium for cell interaction. Extra of this causes edema.
    extra cellular material; tissue fluid
  18. comes from the cells. Provides a medium for cell interaction and support for the cell. MATRIX is this.
    extra cellular material; intercellular substance
  19. How cells stick together
    intercellular junctions
  20. the nails that connect cell to cell
    tonofilaments
  21. the head of the nail
    attachment plaque
  22. a junction between cells
    desmosome
  23. a junction between a cell and a non cellular surface (i.e. the oral epithelium and the surface of the tooth)
    hemidesmosome
