Witryna17 sty 2024 · Action potential is a brief reversal of membrane potential in which the membrane potential changes from -70mV to +30mV. The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage … WitrynaThe nerve impulse first starts at the dendrites, then arrives at the cell body, which contains the nucleus of the neuron. The red arrows in Figure 1 show the path that the nerve impulse will take from the cell body and along the threadlike part of the neuron called an axon. Some neurons, like the one in Figure 1, have an insulating layer ...
