Question

Which sequence correctly reflects the order in which electrical charges occur during an action potential, from first to last?

a. resting potential > action potential > threshold potential
b. action potential > threshold potential > resting potential
c. resting potential > threshold potential > action potential
d. threshold potential > resting potential > action potential?

Answer 1

This sequence refer to how neurons send messages electrochemically. When the neurons are at rest, they are at its resting potential at -70 millivolts. If the neurons in the brain send messages, a spike would occur until it reaches the threshold potential at -55 mV. If it reaches the threshold potential, then an action potential occurs.Hence, the sequence would be letter C.
