Is an action potential fired in response to any nerve stimulus?

No, there must be a sufficient voltage summed up from all the inputs to be at or above the trigger voltage. Usually a single input is not sufficient.

What is sub threshold Depolarization of nerves?
Subthreshold depolarization refers to a small increase in the membrane potential of a nerve cell that does not reach the threshold for generating an action potential. It is a graded response that occurs when the membrane potential of the nerve cell approaches but does not exceed the threshold for firing an action potential. Subthreshold depolarizations can summate or integrate within the cell to reach the threshold and trigger an action potential.
What is the value of Canadian centennial 3030 never fired?
Providing it has everything that originally came with it and has never had the action cycled you are in the 800-1200 range.
What is the point of rotating bolt design?
It delays the blowback action in order to wait while the pressure from the fired round drops to a safe level.
What does unexploded mean?
Unexploded is an adjective meaning "intact, not ruptured, having the potential to suddenly release a large amount of energy". It is generally used in reference to ammunition that was fired but did not ignite or detonate.
Necessary features are sponges or cnidarians lacking in order to have a more mobile lifestyle?
Stimulation is needed to make sponges more mobile. Once the senses are heightened, a rapid response is fired in cnidarians which triggers movement.
What is the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
What is reaction time in pe?
PE Theory definition: Reaction time is the name given to the ability to react quickly to an action e.g: reacting to the sportsgun being fired at the begining of a race.Scientific defintion: The time elapsed between a stimulus and an the response to it ( the effector).
How does the end plate potential differ from a EPSP on a post synaptic cell?
End plate potential is the change in potential from neurotransmitters. It can be excitatory or inhibitory. If the action potential wants to continue, it will be excitatory and vice versa. It can be additive, if more action potentials are fired it will increase the end plate potential. An action potential is an all or none response. It will either proceed or it will not proceed depending on the terms of the threshold. It cannot be additive, because there is an absolute refractory period where no additional action potentials can be fired.
How does a neuron indicate the strength of a stimulus?
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
Why does action potential's move through axons in only one direction?
the axons and dentrites would get mixed up and the brain would be thinking in two ways and we would be confused to which one was which

Can an former employer you were fired from tell potential employers 1 that you were fired and 2 why you were fired If not and this happened is there any legal action that can be taken this is in CA?
Doing that opens the former employer up to legal action if it can be proven. You should consult a lawyer. Actually, the employer has zero liability for defamation if it made a factual statement. "We investigated and then fired Jim for misconduct" is a factual statement, which cannot be liable or slander. The employer is not guessing about your motives, nor doing anything butdescribing ITS actions and motives honestly.
Does the glock 17 gen 4 only come in double action or can it come in the double action single action version too?
It only comes as a striker fired pistol - the design cannot accommodate a SA-type action (and the existing action isn't DA, to that end, as the striker fired mechanic is much different from a hammer fired mechanism).
What could happen if immediate action is applied and the m4 carbine is fired with a bullet stuck in the barrel?
It'll render the weapon inoperable, make the barrel pretty much useless, and there's the potential for injury or death to the firer
What is fired when an animal performs an action or when the animal observes that same action being performed?
Mirror neurons
What condition is neuron in when the outside of the neuron has a net positive charge and the inside has net negative charge?
This is called the resting potential (inactive state) of the neuron. However, when a neurotransmitter binds to receptors, electrical stimulus is applied, etc. to induce an opening of ion channels in the membrane of the neuron, positive ions rush into the neuron from the outside to the inside, and result in a sharp increase of the positive charge density (due to more positive ions) inside the neuron. Beyond a certain threshold, this can induce the creation of an action potential, causing the neuron to fire. After the action potential is created, and the neuron fires, there is a short refractory period where the neuron cannot be fired again due to stimuli, when positive ions are pumped back out of the neuron, negative ions are brought into the neuron, and then the ion channels close, leaving the neuron in a polarized state, and returning it to a resting potential.
