Section 11.2 Part 2 Flashcards
1
Q
ion channel
A
a protein embedded in the plasma membrane that allows ions to pass through it
2
Q
resting potential
A
the voltage difference across a nerve cell membrane of an unstimulated neuron; usually negative
3
Q
action potential
A
the voltage difference across a nerve cell membrane when the nerve is excited
4
Q
threshold potential
A
the potential at which an action potential is generated by a neuron
5
Q
refractory period
A
the period of time during which the threshold required for the generation of an action potential is much higher than normal
