How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Where do most action potentials originate?
initial segment
Can action potentials be summated?
no but generator potential can be summated
Why do not action potentials occur during the repolarization phase?
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
Do action potentials become weaker with distance?
action potentials are non-decremental and do not get weaker with distance.
Which electrolytes are important in action potentials and the excitability of nervous and muscle tissue?
Na,K and Ca
Do action potentials in the same neuron come in different sizes and shapes?
Yes, but that is not relevant. The important thing is the frequency of action potential
Someone who is controlling the action of other is using?
Someone who controls the actions of others is using coercion.
What do intercalated discs transfer from cell to cell?
action potentials, ionic currents, the force of contraction and ionic currents and action potentials only
What are the primary application for tasking tracking controlling and routing Top-5 and staff actions?
joint staff action process
How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Communication in the nervous system depends on?
action potentials
Does nervous tissue generate action potentials?
Yes.
Where do most action potentials originate?
initial segment
A nerve impulse consists of a wave of?
Action Potentials
Can action potentials be summated?
no but generator potential can be summated
