If you touch a spark plug fire it won't fire no matter how hard you touch it. They just don't function that way. There are other steps involved. They get their juice from a distributor.
How about neurons? Shouldn't they be the same. My understanding is that there needs to be some sort of chemical communication (neurotransmitters) at the synapse level in order for pain or any other neural action to be created. How will just simply touching the myelin sheath and/or node of ranvier of a nerve cell cause it to fire? I know just a little bit about neurology. Does somebody know if pain can be created simply by touching a nerve?
Some more thoughts on this. Unless the axon hillock of a neuron receives the right stimulus, the sodium/potasium pumps won't get started. Pressure won't cause the axon hillock to receive the required signal. Therefore, it makes no sense to me that a bulging disc etc. can cause a nerve to create the sensation of pain.
If it gets damaged some, there might be some inflamation. But this is hardly the same thing as the sharp piercing pain people experience.
