Novocain, or procaine, is a chemical that dentists use to numb your mouth before drilling. The chemical blocks the sodium gates on sensory neurons, preventing them from opening. Describe how this chemical decreases (One hopes!) the perception of pain
What will be an ideal response?
Because the chemical prevents sodium gates on the sensory neuron from opening, no sodium enters the neurons. Sodium entering neurons is the signal for nearby channels to open, continuing the spread of sodium influx down the length of the axon. If sodium is blocked from entering voltage-regulated gates, the signal or action potential cannot move down the axon of the sensory neuron; thus, the brain won't be alerted to the sensation of pain.
