So let's see how this signal actually takes place. So let's suppose I apply pressure onto my finger. As I apply the pressure, the dendrites of our sensory neuron contains special pressure receptors. And when I apply these receptors are basically these receptors basically create a force. That force creates the oscillation, the movement of our ions, and that ultimately creates our electric current, the action potential. And so the action potential travels, our electric current travels through the axon.
