Depolarization occurs when a stimulus opens sodium channels which allow more sodium to go into the membrane making it less negative and more positive (toward reaching threshold). An action potential can only occur once the membrane reaches threshold which means it has reached the level needed through depolarization. An action potential is a brief reversal in polarity of the membrane making the inside more positive and the outside more negative, the reverse occurs again once the membrane reaches resting potential.
Action potential is a quick depolarization followed by a repolarization. Depolarization is a one way trip. It also takes a substantial depolarization to cause an action potential.
Indeed. You have saltatory conduction because of the presence of myelin in peripheral nerves, laid by Schwann cells. How AP is generated is via the following: WHen threshold potential is reached , voltage gated Na+ channels open, allowing huge Na+ influx. THis is called rapid depolarization. This is followed by a plateau phase, where the membrane potential is relatively flat because slow Ca2+ influx equalizes K+ efflux. The last thing is repolarization which is going to a negative membrane potential because more K+ channels open, Ca2+ channels closing and Na/K+ pump (Na+ pumped out, K+ in)
neurotransmitters from the presynaptic neuron must be released and binded to the ligand gated sodium channels to increase the membrane potential (increase the charge) until it reaches the threshold of the trigger zone which is -55 millivolts.
They're not the same thing, potential energy is energy at rest whereas kinetic energy is energy in motion.
The nearest that I can desribe this action would be "Adaptation".
These terms essentially mean the same thing. It is both and base and an alkali.
Yes, but that is not relevant. The important thing is the frequency of action potential

Affirmative action aims to address historical discrimination and promote diversity in education and employment. It can help level the playing field for marginalized groups who have faced systemic barriers. By promoting equal opportunities, affirmative action can create a more inclusive and representative society.
Ions flow into the neuron. An action potential forms moves along the neuron. A response occurs, here, an aversion response... your body pulls your hand and finger away.
The critical thing to remember about such terms as activism and restraint is that they are (
a thing that is a thing
A bad thing that might happen
Not a thing!
no
No such thing. It is a contradiction in terms. They are opposites.
In grammar, "person," "place," and "thing" are known as nouns. Nouns are words used to name a person (like "Mary"), place (like "Paris"), or thing (like "book"). They can be used in sentences as subjects, objects, or to show possession.
