Identify the correct sequence of steps in the generation of an action potential. 1. Activation of sodium channels and rapid depolarization 2. Inactivation of sodium channels and activation of potassium channels 3. Depolarization to threshold 4. Closing of potassium channels

The sequence is: 3,1,2,4

Explanation:

It is understood as the potential of action to the electric wave that originates from the changes that the neuronal membrane undergoes due to the electrical variations and its relation between the external and internal means of the neuron. It begins in the axon cone, where a large number of sodium channels are observed. Its phases are as follows:

-resting potential

-depolarization

-repolarization

-hyperpolarization

-resting potential

-the potential for action and release of neurotransmitters
