(short answer) Describe the process of cellular depolarization.

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.
