What is the time between the action potentials?
Called an interspike interval
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
Why does artifact always appear ahead of action potential?
Why does artifact always appear ahead of action potential?
When the interval between the stimuli decreases a second action potential is generated how?
When the interval between stimuli decreases, the membrane potential of the neuron has not fully returned to its resting state before the next stimulus arrives. This allows the neuron to quickly reach the threshold for generating a second action potential without returning to baseline. This phenomenon is known as temporal summation, where the combined effect of multiple stimuli within a short time frame can lead to the generation of subsequent action potentials.
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
What is the absolute refractory period?
Absolute Refractory Period:It is the interval during which a second action potential absolutely cannot be initiated, no matter how large a stimulus is applied.ORAfter repolarization there is a period during which a second action potential cannot be initiated, no matter how large a stimulus current is applied to the neuron. This is called the absolute refractory period, and it is followed by a relative refractory period, during which another action potential can be generated
What was the effect of curare on eliciting an action potential?
It creates an action potential
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
What is the time between the action potentials?
Called an interspike interval
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Why does curare create an action potential?
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Also called a nerve impulse transmitted by axons?
action potential
What is the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
