Repolarization

Question 1

Repolarization:

Answer 1

The RETURN to the resting-membrane potential state

Question 2

when does repolarization occujr:

Answer 2

after the depolarization occurs

Question 3

After the cell-membrane has fully depolarized the POTSSIUM CHANNELS?

Answer 3

potassium channel OPEN

K ions are repelled by the pos. charge in the ICF

K ions exit cell to go into the ECF

Question 4

END result:

Answer 4

the cell membrane repolerizes

ICF is now neg charged

ECF is now positive charged

NA/K pump returns the neuron to the resting-membrane-potential
