Question

During the transmission of nerve impulse through a nerve fiber, the potential on the inner side of the plasma membrane has which type of electric charge ? 

Options

A.First negative, then positive and sgain backto negative
B.First positive, then negative and continue to be negative
C.First negative, then positive and continue to be negative
D.First positive, then negative and again back to positive

Solution

During the transmission of nerve impulse through a nerve fiber, the potential on the inner side of the plasma membrane has first negative, then positive and again back to negative by re-polarization.
