Explain why the threshold voltage is not always the same value between axons and within an axon?
Each region of the neuron contains distinct membrane proteins that provide the basis for the threshold differences.
Factors that effect reaction time?
The sensitivity of the receptors, velocity of nerve conduction, and the number of neurons and synapses involved to name a few.
How do electrons flow in an electric circuit in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
What is the influence of gate voltage on drain source breakdown voltage in mos transistors?
Drain-to-source breakdown voltage (BVdss) should not change appreciably until the gate-to-source voltage (Vgs) approaches the device's threshold voltage (Vth). In that case, the drain to source voltage becomes the product of the drain-to-source current (Ids) and the device's on-state resistance (Rds-on) at the given Vgs.
What is the cut in voltage of germanium and silicon diodes?
cut in voltage *** for silicon is 0.7volts and that for germanium is 0.3volts.According to Millman and Taub, "Pulse, Digital and Switching Waveforms", McGraw-Hill 1965, the cutin (or offset, break-point or threshold) voltage for a silicon diode is 0.6, and 0.2 for germanium.Breakdown voltage is another thing entirely. It is the reverse voltage at which the junction will break down.
What is a threshold voltage in scr?
the voltage at which the current conduction occur

What is threshold voltage in neve conduction?
From resting, -70mv to firing level -55mv ie 15mv.
Is conducting stimulus strong enough to generate a nerve impulse?
It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.
If the position of a nerve was reversed and its conduction velocity recorded would it be the same as if it were not reversed?
Nerve conduction is the same in both directions. The rate of conduction is mediated by the physical properties of the nerve and the voltage sensitive channels so as long as the diameter is constant the spread of the action potential would be the same in either direction.
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?
when the voltage of the stimulus is increased above threshold, it can instantly trigger the action potential into a depolarizing state which will rapidly shoot up above the threshold value.
What is the lowest stimulus voltage that induces active force in the skeletal muscle?
It is called the threshold voltage and is around -70 mvolts.
What do nerve conduction velocity studies?
Nerve conduction velocity studies (NCV) are used to measure the speed with which an electrical signal is transferred along the nerve.
Difference between Threshold voltage and knee voltage?
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
What is nerve conduction velocity test?
Nerve conduction velocity test-- A test that measures the time it takes a nerve impulse to travel a specific distance over the nerve after electronic stimulation.
Why does the nerve action potential increase slightly when you add 1.0 V to the threshold voltage and stimulate nerve?
The action potential increases slightly because more neurons are being stimulated.
