Local anesthetic is often used in dentistry to lessen the sensation of pain during dental procedures. It prevents propagation of nerve conduction by decreasing the flow of ions. a. Describe how depolarization of an action potential can be blocked by the use of local anesthetic. b. Your classmate explained that once the threshold potential has been reached, the inside charge of the neuron is more positive than the outside charge. Is she correct? Can you compare the inside charge to the outside charge in an axon treated with local anesthetic?
