What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):
