I WONDER - How Do The Fingers Move?

The video explains that finger movements are not controlled by muscles in the fingers themselves, but by muscles located in the forearm and palm, known as extrinsic and intrinsic muscles. These muscles are connected to the finger bones by tendons, which are strong and flexible cords. When the muscles contract, they pull on the tendons, causing the fingers to move. This system allows for precise and powerful finger movements.

What happens when the muscles contract?
