What is the sequence of events that correlates to the sequence of events of a nerve impulse?
2,1,3,4
Sequence of events in one heartbeat?
the blood goes in one direction
Sequence of events that would lead to a person hearing a sound?
transduct, amplify, transmit, integrate
What is the definition of time in scientific terms?
The dimension of the physical universe which orders the sequence of events at a given place; also, a designated instant in this sequence, such as the time of day, technically known as an epoch, or sometimes as an instant.
How do you know when you have crossed the threshold of a mechanical device?
how do you when you have crossed a threshold for a mechanical device
What is the sequence of events that follow a threshold potential?
Death.
What is a sequence of rapidly occurring events that decrease and reverse the membrane potential and then eventually restore it to the resting state?
Action potential or impulses
What sequence of events occurs when an action potential arrives at the presynaptic terminal?
calcium ions to diffuse into the cell.
A neuron fires only when its membrane reaches what?
When it reaches the nerve impulse threshold, the next neuron will fire..
What do you call events that occur in a sequence?
You call them 'sequence of events'.
The minimum stimulus needed to cause a contraction is called the?
threshold stimulus
What is the sequence of events that correlates to the sequence of events of a nerve impulse?
2,1,3,4
Membrane potential required to achieve threshold?
-55mV
In this excerpt the sequence of events creates suspense by?
In this expert the sequence of events creates suspense by ?
Minimum level of stimulation required to trigger a neural impulse?
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.
When several neurons are stimulated equally which one will fire first?
The neuron with the lowest threshold potential will fire first when several neurons are stimulated equally. Threshold potential is the minimum level of depolarization needed to trigger an action potential in a neuron. Neurons with lower threshold potentials are more excitable and will fire before neurons with higher threshold potentials.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
