Nettie is in the laboratory working with cultured neurons. She wants to record the voltage following the opening of the sodium channels. What does she need to do to get the sodium channels to open?
A) Add a solution that will result in depolarizing the membrane.
B) Add a solution that will result in hyperpolarizing the membrane.
C) Increase the amount of sodium outside of the neuron.
D) Produce an action potential and get to the refractory periods.

Question

Quizplus · Accepted Answer

The opening of sodium channels is a result of depolarization of the neuron. By adding a solution that depolarizes the membrane, Nettie can trigger the opening of sodium channels and record the resulting voltage changes.
