Schematic diagram: When I happen to step on a pointed object I immediately remove my feet as I feel a sharp piercing pain under my feet.
This happens due to reflex action presents in all humans.
The nerve rejector below my feet is activated and sends an impulse transported by neurons located in the spinal chord.
The reflex action transmits a message via motor nerves to remove the feet.
Nerves carry that impulse to a receptor of sense, that is present under my feet. as a consequence, I move the feet away.
