Ring finger interactions with pinkie
Ring finger interactions with pinkie
I recently heard that the nerves controlling the pinkie and ring finger are intertwined to the degree that it's almost impossible for most people to move the pinkie and ring fingers without the other. Does it count as "independent" if one twitches while the other does the real moving? I think I may finally be special!

It's not nerves, but ligaments and tendons that are linked, in basic terms.
One can feel/see this my making a fist with the ring finger extended then manipulating it with the other hand. Or having some one else gently manipulate it
Yup, we basically puppeteer our fingers with muscles that are in our forearms and smaller muscles for fine movements (like side to side movements ) in your palm. Apparently there are also muscles that curl your fingers at the top part of your palm, but they're assisted by tendons that connect to your forearm and also pull when flexing.

No muscles in our actual fingers, they just have bone, fat, tendons, nerves, blood vessels, and lymphatic system "stuff".
