Your Answer: each stimulus incerases flow of na+ into cell then causes positive shift in the membrane, then an action potentional is formed. that one stimulus will cause depolarization that then reaches threshhold level. once threshhold is reached positive feedback loop is used and more sodium flows into teh cell which shifts membrane potential. Sodium channels open and sodium flows into the cell causing a more positive shift in membrane potential (+62mV), and an action potential is generated. Correct! Quiz Score: 100 out of 100 Show Less
