Imagine it takes a 100 mV depolarization change to produce an action potential.Which of the following should result in an action potential?
A)inhibitory signals equaling approximately 110 mV
B)excitatory signals equaling 75 mV plus inhibitory signals equaling 25 mV
C)excitatory signals equaling 110 mV
D)inhibitory signals equaling 75 mV plus excitatory signals equaling 25 mV

Only excitatory signals equaling 110 mV would produce a depolarization change of 100 mV or greater, which is the threshold for an action potential. Inhibitory signals and a combination of excitatory and inhibitory signals that do not reach this threshold would not result in an action potential.
