Question

Quizplus · Accepted Answer

When Sara squeezes Scott's hand very hard, the nerves in his hand will start to fire at a faster rate. This is because the increased pressure on the nerve cells will depolarize them, leading to the opening of voltage-gated ion channels and the propagation of an action potential down the axon. As a result, the nerve cells will fire more frequently and send stronger signals to Scott's central nervous system.
