Nerve impulse conduction
The study found that nerve cell There is a potential difference between the inside and outside of the plasma membrane. In the resting state, the inside of the membrane is negative and the outside of the membrane is positive, which is called membrane potential. It is maintained by k ions inside the membrane and Na ions outside the membrane. When stimulated, Na ions in local areas (excited areas) flow into cells, and the potential is negative in any case, which means excitation (nerve impulse). At this time, there is a potential difference between the excited area and the adjacent part, which will cause the adjacent part to produce excitation, and the excitation will advance along the nerve fibers, which is called nerve impulse conduction. It can be seen that information is transmitted in the form of bioelectricity on neurons. direction
