Why is it almost impossible to raise your ring finger on its own, when the pinky, index, and middle finger don’t have these issues?

Answer 1

The tendons that control the ring finger are connected to the same muscle group as the tendons that control the middle finger, making it difficult to move the ring finger independently. In contrast, the pinky and index fingers have their own muscle groups, which allows for more independent movement.
However, by practice and training, some people can improve their ability to move the ring finger on its own.
