Synaptic Transmission F214

Quiz on the steps of Synaptic Transmission in a cholinergic synapses. 

?

1. What is the correct definition of "Threshold Potential"?

  • The minimum amount of ions in a transmission.
  • The membrane potential to which a membrane must be repolarized to stop an action potential.
  • The membrane potential to which a membrane must be depolarized to initiate an action potential.
  • The maximum amount of impulses that can be sent at one time.
