image The paralysed finger

Try this...it is impossible to lift your ring finger.

Essentially your index finger and pinky have independent extensor tendons whereas your middle and ring finger share one.

The index and small finger each have independent extension function through the extensor indicis proprius and extensor digiti minimi.

There you go, now you know.  Maybe you can win some bets at a bar now...
