In your fingers no muscles

Human fingers have no muscles. We are moving them with the remote control, so to speak.

Use your fingers to move the tendons of the forearm muscles controlled. When we need to, for example, to bend the finger, forearm muscles pulled tendon, acting on the basis of their puppets. In total, the process involved 17 and 18 palm muscles - the forearm.

Even in the thumb muscles have. It is very strange that the fingers of one of the most moving parts of the human body itself is unable to move.
