Why does a cut hurt when exposed to salt?
In: Biology
Nerves are powered by salt. A nerve impulse is a wave of salt ions crossing gates in the outer membrane of the nerve travelling along its length. Nerves are polarised and are supposed to allow sodium ions through the gates if prompted by their neighbouring nerve. When you add salt the sudden presence of way too much sodium overloads the gates, and an impulse is triggered. Since there are a lot of pain nerves under our skin, they are the ones that stimulated.
This is the same reason why adding salt to very fresh meat causes it to twitch. The salt stimulates the muscle nerves.
It doesn’t hurt anyone but you. The only logical conclusion is you are secretly a conglomerate of slugs pretending to be a person.
