An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
The minimum level of stimulation required to trigger a neural impulse is called the Threshold.
The minimum level of stimulus that is required to active a neuron is called the neuron's threshold. The neuron's reflex is its response to stimulus.

The nerve impulse (action potential) either occurs, or it doesn't, depending on whether or not a sufficient summation of inputs from dendrites at the axon hillock (the trigger point) has occurred, either temporally or spatially.That is, if a large enough number of dendrites have received inputs from other neurons such that their total contribution of electrotonic impulses to the axon hillock results in enough Na ions there to trigger the action potential, or, if one or more dendrites is/are stimulated so often or quickly that, again, there are enough Na ions pushed to the axon hillock to trigger the action potential, then the nerve will "fire". If not enough Na ions are caused to congregate at the axon hillock by either means, then the action potential will not occur, and there will be no transmission of a nerve impulse.
Nerve impulses, which are electrical, do not jump across the synaptic gap at synapses. Instead, the arrival of a nerve impulse at the axon terminal triggers the release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the chemicals to the place where it needs to go to
It can trigger a tsunami.
yes it is
Yes the tsunami did trigger the nuclear blast because the water got into the nuclear reactor and buggered it up
threshold stimulus
Bootje patrick...bootje
It means the minimum current can trigger the SCR to operate.
Action potential is nerve impulse triggered when a neuron reaches its threshold, or trigger point for firing. Threshold trigger point for a neuron's firing about negative 50 millivolts.
sensory responce is sort of like your taste buds they trigger a sence on what kind of foods that u like and foods that u dont like! :)
We have sympathetic and parasympathetic nerves. When we are fightened or scared, sympathetic nerves trigger impulse into the brain in order to release adrenaline. This adrenaline makes the heart beat faster because more oxygen is required. This helps us cope from stress.After a while parasympathetic nerves send impulse to reduce the release of adrenaline and the heart starts beating normally
Stimulation of the face, lips, or gums, such as talking, eating, shaving, tooth-brushing, touch, or even a current of air, may trigger the severe knifelike or shocklike pain of trigeminal neuralgia.
It is a ramping mode that, as a minimum trigger pull speed is achieved, the marker rolls over into fully automatic for as long as minimum bps is kept.
it is sent through the neurotransmittersAt the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.
Latching Current is the minimum current needed on the gate to fire or trigger an SCR.
A flip flop is a quiescent component meaning it can have one of two states A trigger or signal is required to force the flip flop to change state
SA - pull trigger and weapon fires. Manual reset of hammer required. DA - pull trigger and weapon fires, pull trigger and weapon fires; repeat until ammunition expended.
