Card Set Information
Increase in negativity of the resting potential of a cell membrane, further from threshold.
Getting closer to the threshold.
Unlike action potential this is not an all or nothing response
An all or nothing response, when the threshold potential is reached this is triggered.
The last site in the soma where membrane potentials spread from synaptic inputs before being transmitted to the axon.
Level of potential at which an action potential is triggered in a neuron.
Sensitive part of an axon where an action potential is generated.
Being charged differently on both ends.
The membrane of a neuron becoming less negative ( more positive) then the resting potential.
The membrane of the neuron becoming more negative (less positive) then the resting potential.
Period following stimulation during which a neuron or muscle fiber will not respond to another stimulus.
A response that occurs completely or not at all.
lasts 1/2,500 of a second, the axon can not be stimulated.
absolute refractory period
Is now reestablishing its resting potential, but may be stimulated by higher then usual intensity, triggering an impulse.
relative refractory period.
