During the ___________ ____________l, a reverse in electrical
charge occurs across the membrane of a neuron in its resting
state. - Correct Answers ✅During the action potential, a
reverse in electrical charge occurs across the membrane of a
neuron in its resting state.
Which ion helps establish an action potential along an axon? -
Correct Answers ✅Electrical impulses travel along the
axon of a neuron when the inside of a cell is positively
charged and the outside of a cell is negatively charged. This
difference in charge is due an exchange in the flow of sodium
and potassium ions in and out the cell.
