Bryson is having a cavity filled at the dentist and was given Novocain to prevent feeling any pain. Later, he explains to his roommate how the Novocain worked to stop the pain. What did he tell his roommate?

Bryson told his roommate that Novocain works by binding to the sodium channels on the axons of neurons and prevents sodium from entering. Because sodium cannot enter the axon, the neuron cannot produce an action potential. Therefore, the pain message was never sent to Bryson's brain from his mouth.
