Biology multiple choiceWatch
A. The magnitude of an impulse is always the same
B. After one impulse there is a refractory period when the axon cannot
C. A nerve impulse can pass along an axon in one direction only
D. It has a threshold below which it cannot be stimulated
E. The resting potential of an axon is - 70mV
The answer is B but i am confused why. I thought that the whole point of the refractory period was to make it impossible for further action potentials to be generate (as the sodium voltage gated channels are closed)?
