How does electrical impulses travel in the human body?

We all know that information travels in the form of electrical impulses through one nerve cell to the other and reaches the brain (or may be spinal cord in the case of reflex arc).

Let’s learn this process in a bit detail.

The information acquired at the end of the dendritic tip of a neuron sets off chemical reaction which creats electrical impulses which then passes through the cell body, axon and reaches the axon terminal where the electrical impulses sets off the release of some chemicals which then pass a gap or SYNAPSE and reaches the dendritic tip of another neuron. This process continues till the impulse reaches the brain.
