Organs that you can control at will?

A person can consciously control most of the muscles in the body. Flexion of arms, legs, turns of the neck and trunk, facial expressions, clenching of the jaws, fine movements of the fingers are available for complete control. A person is also able to consciously blink, hold or quicken his breathing, although these processes usually occur unconsciously. We can also control the work of the brain to a large extent – focus on an object or task, imagine something that does not exist, remember an event.
