Adding sodium chloride increases the concentration of sodium ions outside of the cell. This means that the concentration gradient is increased even more than what is usually the resting potential and with that as the driving force, a action potential occurs the same way as if the channels opened up from an electropotential.
What else can I help you with?
Why does the addition of ether elicit an action potential?
Ether can transmit inhibitory effects.
What kinds of stimuli can elicit action potential?
Electrical , heat and chemical stimuli
Define the period of repolarization when only a strong stimulus will elicit an action potential?
The period of relative refractory period is the time after an action potential during which a strong stimulus is required to generate a new action potential. This is because the membrane potential is hyperpolarized, making it more difficult to reach the threshold for firing another action potential.
What is relative refactory period?
The relative refractory period is the phase of the cardiac action potential during which a stronger-than-usual stimulus is required to elicit another action potential. It occurs immediately following the absolute refractory period and allows for the heart muscle to be able to respond to a second, stronger stimulus after the initial action potential.
Make a sentence using the word elicit?
My innocuous question was intentionally posed with the intent to elicit a more forthcoming response from the witheringly hostile witness. The chemist's addition of certain chemicals to the mixture may elicit an unwanted reaction.
What is the supranormal period cardiovascular?
Supranormal Period (SNP) is the period during which a slightly smaller than normal stimulus can elicit a propagated response, although the amplitude of the action potential is reduced compared to normal. I'm not sure either as of to how the mechanism of this allows a stimulus lower than threshold can elicit this response.
What is the product of rheobase and chronaxie - either charge or volt?
The product of rheobase and chronaxie is expressed in volts. Rheobase is the minimum current required to elicit an action potential, while chronaxie is the time required for a current twice the rheobase to stimulate the tissue. Multiplying these two parameters gives a measure of the voltage required to elicit a response in excitable tissues.
Which period whereby no impulses can be generated even with intense stimulation?
The period during which no impulses can be generated, even with intense stimulation, is known as the absolute refractory period. This occurs immediately after an action potential when sodium channels are inactivated and cannot reopen, preventing any new action potentials from being initiated. Following this is the relative refractory period, during which a stronger-than-normal stimulus is required to elicit an action potential.
What is the cause of compensatory pause after an extrasystole?
Extrasystole is due to the irregular contraction of the ventricle before the atria. When this happens, an action potential is elicited and the ventricle contracts. The action potential had a refractory period, during which the intrinsic heart rate attempts to fire but cannot elicit a contraction. This is why extrasystole is often referred to as skipping a beat. The compensatory pause is the time it takes for the beat to resume normal contraction.
Which term refers to the period whereby no neutral impulse can be generated?
The term that refers to the period during which no neutral impulse can be generated is the "refractory period." This phase occurs after an action potential, during which the neuron is temporarily unresponsive to further stimulation. It is divided into the absolute refractory period, where no new action potential can be initiated, and the relative refractory period, where a stronger-than-usual stimulus is required to elicit a response.
What is a stimulus that results in no perceptible contraction?
A subthreshold stimulus is one that does not generate a strong enough signal to elicit a perceptible contraction in muscle fibers. It is below the threshold required to cause an action potential and result in muscle contraction.
What is the meaning of elicit?
What you are trying to do is elicit an answer to your question: Elicit is to attempt to obtain. To get, to receive.
