Put the events that occur during an action potential in the proper order.  Start with: The membrane reaches the threshold voltage. 

Activity 7:  The time it takes for an action potential to be conducted from R1 to R2 would be shortest with

Once [x] are converted to [y], the frequency of stimulation is [z] the interspike interval (ISI).

Match the description of forces listed in the left column with the terms found in the right column.

In Activity 6, which of the following will increase the stimulus intensity?

Lidocaine blocks diffusion of [x] through [y] [z] channels.

Put the following events that occur in the axon terminal and at a synapse in the proper order.

In synaptic transmission, which cell is the target cell?

[a] neurotransmitter was released when in the experiment having no Ca++ in the extracellular fluid because [b] is Ca++ dependent.

Mg++ [a] the effect of extracellular calcium by blocking [b] and [c] neurotransmitter release.
