The amplitude is about +35 to +40 Millivolts

I believe this is incorrect, as this would only raise the resting membrane potential from -70mV to -35 or -40. An action potential needs to raise the membrane potential from -70 mV to +30 mV, so the amplitude needs to be 100 mV.

Does a large stimulus produce a higher amplitude in a action poteintial?

No, the amplitude of an action potential is constant and does not vary with the strength of the stimulus. Instead, the frequency of action potentials fired by a neuron can increase with a stronger stimulus.


What do you call the measurements of a wave's magnitude of oscillation?

The measurements of a wave's magnitude of oscillation are called amplitude. Amplitude refers to the maximum displacement of a wave from its equilibrium position.


What does magnitude?

size, amplitude, greatness


Why amplitude is scalar?

Amplitude is a scalar because it is a magnitude that represents the maximum value of a wave. It does not have a direction associated with it, unlike vector quantities which have both magnitude and direction. This makes amplitude a scalar quantity.


What effect did an ether have on action potential?

Ether can enhance the excitability of nerve cell membranes, leading to a decrease in the threshold for action potential generation. This can result in an increase in the frequency and amplitude of action potentials.


What is the relationship between amplitude and magnitude?

* The term peak amplitude, often shortened to amplitude, is the nonnegative value of the waveform's peak (either positive or negative). * The instantaneous amplitude of is the value of (either positive or negative) at time . * The instantaneous magnitude, or simply magnitude, of is nonnegative and is given by . ALSO Amplitude is the maximum displacement from equilibrium in a sinusoidal wave.Magnitude is just the value of something; typically refering to scalar quantities.


How much greater is a magnitude 8 earthquake than a magnitude 4 earthquake in amplitude?

The Richter magnitude scale is a base-10 logarithmic scale of the shaking amplitude. This means that a difference of 1 in the scale is equivalent to a 10-fold increase in amplitude. So the difference in amplitude between a mag 8 and a mag 4 earthquake is 104.


How do you define Amplitude?

Amplitude is the magnitude or strength of a signal, wave, or vibration, typically measured as the distance from the midline to the peak of a wave. It represents the maximum displacement of a wave from its resting position.


How much larger is the wave amplitude of an 8.0 earthquake than a 6.0 earthquake?

The wave amplitude of an 8.0 earthquake is 100 times larger than that of a 6.0 earthquake. This is because earthquake magnitude scales logarithmically, where each whole number increase represents a tenfold increase in amplitude.


Do action potentials always have the same amplitude and the same duration?

Yes, this is due to the all or nothing law that neurons follow: "an excitable membrane either responds to a stimulus with a maximal action potential that spreads nondecrementally throughout the membrane, or it does not respond with an action potential at all." "
