The highest frequency of action potentials generated by the mechanoreceptor is most likely to occur at which of the following receptor potentials (in mV)?
A)-60
B)-50
C)-45
D)-40
E)-35

Question

Quizplus · Accepted Answer

The highest frequency of action potentials in a mechanoreceptor is most likely to occur at the receptor potential closest to the threshold for action potential initiation, which is typically more depolarized (less negative) than resting membrane potential. Among the options, -35 mV is the least negative value, indicating the most depolarized state, and thus, it would likely result in the highest frequency of action potentials.
