Unit 2- Within Neurons Flashcards
1
Q

A
Preparing to activate.
When the inside of the axon is negatively charged and the outside is positively charged
2
Q
Stimulus Threshold
A
The minimum level of stimulation from other neurons to activate it.
PRIOR to stimulation = polarized
ACTIVATED neuron = depolarized
3
Q
Action Potential
A
Brief electrical impulse along the axon to transmit info
4
Q

A
Once it starts it cannot stop
5
Q
Refractory Period
