What else can I help you with?
What is ramp voltage?
Ramp voltage is a voltage that can be steadily increasing or decreasing.
What is the potential voltage?
Unless you are using 'potential' in the general sense (i.e. "What is the possible voltage?"), there is no such engineering term as 'potential voltage'. Voltage is a synonym for 'potential difference', so your expression would then mean "What is the potential potential difference?"Do not mix up 'potential' with 'potential difference' (voltage); they are two different things.
Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
Advantages of dynamic voltage restorer?
hi my question is why to use de DVR end eplain why i do to use the simulation and studieng of the Dynamic Voltage restorer why matlab.
Will changes to the stimulus voltage alter the duration of the latent period?
Yes, changes to the stimulus voltage can affect the duration of the latent period in muscle contractions or neural responses. A higher stimulus voltage may lead to a more rapid depolarization of the cell membrane, potentially shortening the latent period. Conversely, a lower voltage may result in a longer latent period due to slower depolarization. However, the specific effects can vary depending on the type of tissue and its excitability.
Why is the amplitude of the compound action potential recorded from the frog sciatic nerve increased when the voltage of the stimulus was increased above the threshold value?
Increasing the stimulus voltage above the threshold value results in recruiting more nerve fibers to generate action potentials. This leads to a greater number of action potentials being generated simultaneously along the nerve, resulting in a larger compound action potential amplitude being recorded.
The action potential is generated when a stimulus?
The action potential is generated when a stimulus causes a change in the electrical potential across the cell membrane, resulting in the opening of voltage-gated ion channels. This allows an influx of sodium ions, causing depolarization of the membrane and initiation of the action potential.
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.
Can rheobase be a threshold stimulus?
Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.
What opens first in response to a threshold stimulus?
The activation gates of voltage-gated Na+ channels open, and Na+ diffuses into the cytoplasm.
What is ramp voltage?
Ramp voltage is a voltage that can be steadily increasing or decreasing.
During the absolute refractory period an impulse may be triggered by a stimulus of high intensity?
During the absolute refractory period, the neuron is incapable of generating another action potential regardless of the stimulus intensity, as the voltage-gated sodium channels are inactivated. Once these channels have reset during the relative refractory period, a strong enough stimulus can trigger an action potential again.
What does it take to trigger an action potential?
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.
What is the potential voltage?
Unless you are using 'potential' in the general sense (i.e. "What is the possible voltage?"), there is no such engineering term as 'potential voltage'. Voltage is a synonym for 'potential difference', so your expression would then mean "What is the potential potential difference?"Do not mix up 'potential' with 'potential difference' (voltage); they are two different things.
Why are most action potentials generated in response to a long stimulus that is above threshold?
Action potentials are generated in response to a long stimulus above threshold because it allows for the full development of the depolarization phase. This prolonged depolarization leads to the activation of voltage-gated sodium channels, triggering the rapid influx of sodium ions and initiating the action potential. A sustained stimulus ensures that the membrane potential remains above threshold for a sufficient time to generate an action potential.
What is the relationship between amplitude of muscle response and voltage of stimulus applied?
The relationship between the amplitude of muscle response and the voltage of the stimulus is generally linear. As the voltage of the stimulus increases, the muscle response increases in amplitude up to a certain point. Beyond that point, further increases in voltage may not significantly increase the muscle response amplitude or could lead to muscle fatigue or damage.
Is conducting stimulus strong enough to generate a nerve impulse?
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
