6. Alchol makes GABA open longer =

  • further inhibition
  • further excitation
  • further uptake

7. Within neurones there is a..... across membranes

  • testicular flow
  • electrical flow
  • chemical flow

8. AGONISTS

  • stop neurotransmitter effect
  • enhance neurotans effect
  • no effect

9. ANTAGONISTS

  • no neurotrans effect
  • enhance neurotans effect
  • no effect

10. there are..... to empty a synapse

  • active
  • inactive

11. blood brain

  • challenger
  • barrier
  • protector

12. Indirect

  • directly ion channel, changes ahoe channel, pos neg
  • bind other protein changes cell effect ion channel

13. If a cell is positive enough to acceed inhibition

  • inbetween
  • none of the above
  • still positive
  • still negative

14. Just one summation is

  • not enough to causes AP
  • enough to cause AP
  • OK

15. GABA normally binds

  • pos and neg chloride ions
  • neg chloride ions
  • pos chlorine ions

16. if an ion channel is already negative and is inhibited

  • further depolarizes the cell
  • repolarizes the cell
  • stays the same

17. Presynaptic cell can

  • none of the above
  • inhibit a receptor
  • inhibit or excite a receptor
  • excite a receptor

18. Direct

  • bind other protein changes cell effect ion channel
  • directly ion channel, changes ahoe channel, pos neg

19. drugs can work by

  • mimicking function
  • not mimicking function

20. transcient effect means

  • effect a large amount of time in a synapse
  • slays a long time in synpase
  • only effect a short amount of time in a synapse
  • only effect a small amount in a synapse
