How do YOU know your hands are wet?
Magic probably.

it doesn't. that's just magicians tricking you into thinking you have wet hands.

well, you see, I don't personally know the answer but I have faith that some esteemed natural scientist has empirical evidence explaining why it isn't caused directly by God's all-loving personal intervention.

would this still happen if you couldn't feel?

how does your nervous system recognize sounds as "fluid", tones as "warm", "cold" etc.? what are you really asking? are you a person, am I a voice in your mind? have you lost my marbles?

Supposedly a boy with nerve damage in his hand wouldn't get wrinkly on the fingers he couldn't feel.

there are studies on this, and it has been confirmed that patients with nerve damage do not experience wrinkling. the mainstream accepted hypothesis is, i kid you not, traction - an adaptation to improve grip strength under water.

but this does not address OPs question, which is how the nervous system detects water to begin with

Best educated guess is it's not measuring contact with water, but measuring how much water your skin is perspiring or exhaling. Put on some rubber gloves that don't breath well and you'll get the same prune fingers. Perhaps it's possible the fingertips are so sensitive it's the only part of the body capable of sensing water loss in this way.

that sounds reasonable, thank you. OP, there's an answer for you. now please respond and say thank you.

But I was being serious. The nerves tell the hands to decrease circulation to the hands/feet, which causes them to wrinkle. I know it's not the thermoreceptors that do it, because it works the same in hot or cold water, so it must be something else.

When I've done that my hands prune, but they're also really sweaty. I always thought it was because the hands are soaking in trapped sweat that it wrinkles.

What else would it be you tardo

Anonymous at Sat, 6 Apr 2024 22:58:10 UTC No. 16115984

it's a combination of receptors in your brain and skin telling your blood vessels to constrict. you have receptors in your skin and blood vessels that detect changes like chemoreceptors, so it's most likely through a combination of those. probably, I took A&P II and didn't learn about this shit.
