@handtherapy4all: Your wrinkly fingers are actually controlled by your nerves 🤯💧 When your hands are submerged in water, your nervous system causes blood vessels in the fingers to constrict, creating those wrinkles.

Some researchers believe wrinkling may even help us grip wet objects better. 👀 Did you know this? #HandAnatomy #NervousSystem #Anatomy #HandTherapy #DidYouKnow
