Question

Quizplus · Accepted Answer

Local anesthetics like Novocaine work by blocking voltage-gated sodium channels on neurons. This prevents the influx of sodium ions into the neuron, which is necessary for the generation and propagation of action potentials, effectively numbing the area by stopping the transmission of pain signals.
