    an "all-ornothing" event. Explain what is meant by this phrase. This means that once the threshold is met, an action potential occurs. If the stimulus is too small an action potential does not occur. An action potential is usually initiated in an axon at or near what? The axon hillock, the initial segment...

    increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: By increasing the extrecellular K+ the net diffiusion of K+ out the neuron through the eak channels is reduced. This is caused by the flow of ions following the concentration gradient of traveling...
