  1. Neurophysiology ? ? ? ? ? ? Label this diagram

  2. 1 2 3 4 What happens at each stage on this graph?

  3. Which graph is Depolarization? Which one is Hyperpolarization? ? ?

  4. Which highlighted area is Absolute refractory period? What is the other period called?

  5. What is happening at each step? What is this area called? Step 1 What kind of channels are these? Voltage gated channels Step 2 What about these? Step 3 Step 4 Chemically gated channels Step 5 Step 6

  6. 1. Which graph represents Excitatory postsynaptic potential(EPSP)? 2. Which one is inhibitory postsynaptic potential(IPSP)? What is EPSP? ? What is IPSP? ?

  7. Ion Channels Which picture is represented by each? What is the difference between Chemical gated ion channels And voltage-gated ion channels? Answer Voltage-gated ion channels Chemical gated ion channels: Chemical gated ion channels: Open when the appropriate neurotransmitter binds to the receptor Voltage-gated ion channels Open and close in response to changes in membrane voltage

  8. Matching: Select which one is graded potential and which one is action potential 1 2 3 4 END SLIDE

  9. back 1. Location of event Graded potential Action potential Cell body and dendrites Axon hillock and axon

  10. back 2. Distance traveled Graded potential Action potential Short distance Long distance

  11. back 3. Initial effect of stimulus Graded potential Action potential

  12. back 4. Peak membrane potential Action potential Graded potential

  13. The End!! Presentation by: Jessica Long JoselynCoakley Marsia Martin Powerpoint by: Jessica Long With special thanks to: Human Anatomy and PhysiologyEighth Edition www.myaandp.com Dr. Hammoudi And our wonderful audience!!
