Really? Why?
- mondoshawan 8y agoBecause the middle, ring, and pinky all share the same muscle group. Try this: hold your hand out in a fist and extend your middle, ring, and pinky straight out. Now try to flex each of the three extended fingers individually without moving the other two. Now try the inverse: make a fist and try raising each finger individually without moving the other two. It's physiologically impossible because the muscle used for extension is shared between those fingers. (Edit: extension is impossible, not contraction)
