  1. ´╗┐Movement of particles from an area of higher concentration to an area of lower concentration.
    Simple diffusion
  2. Process by which foreign particles are removed from a cell by phagosomes which engulf and digests the foreign body.
    Phagocytosis
  3. Cytoplasmic vesicle which engulfs foreign particles within a cell.
    Phagosome
  4. Process by which a cell engulfs droplets of fluid from its surroundings.
    Pinocytosis
  5. Selective cellular uptake of molecules that bind to a specific receptor.
    Receptor mediated endocytosis
  6. The process whereby part of the membrane is internalized and then reincorporated into the plasma membrane.
    Membrane recycling
  7. Vesicular processes that release material from a cell.
    Exocytosis
  8. The combination of receptor-mediated endocytosis and exocytosis that moves particles through a cell.

  9. Vesicular processes that bring matter into a cell.
    Endocytosis
  10. The difference in electrical charge across a membrane.
    Electrical gradient
  11. A stable voltage across the plasma membrane of an unstimulated.
    Resting membrane potential
  12. A shift in electrical potential across a plasma membrane to a value more negative than the RMP, tendidng to inhibit a nerve or muscle cell.
    Hyperpolarization
  13. A shift in electrical potential across a plasma membrane to a value less negative than the RMP, making a muscle or nerve cell easier to excite.
