Anatomy & Physiology: Nerve Impulse Conduction What is the first step in nerve impulse conduction? - ANS Nerve fiber has resting potential by diffusion of Na and K down their concentration gradients. What is the second step in nerve impulse conduction? - ANS Neurons receive stimulation, causing local potentials which may reach threshold. What is the third step in nerve impulse conduction? - ANS Sodium channels in a local region of the membrane open. What is the ...

How do local anesthetics block the nerve impulse from reaching the brain? By permanently depolarizing the nerve cell membrane By overwhelming influx of fluoride ions By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation By causing massive neurotransmitter release without uptake. By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation How do local anesthetics stop working? By diffusion of the lo...
