Question

how does nerve impulse travel in our body

Answer 1

=>All information from environment is detected by the specialised tips of some Nerve cells.

=>This information required at the end of the dendritic tip of a Nerve cells sets off chemical reactions that creates an electrical impulse.

=> This impulse travels from the dendrite to the cell body and then along the axon to its end.
At the end of the axon, the electrical impulse sets off the release of some chemicals.

=> These Chemicals cross the gap, or synapse, and start a similar Electrical impulse in a dendrite of the next neuron.

In this way nervous impulses travel in the body.
