motor control

It is said that a human body has nearly 800 to 1000 articulations. And each articulation needs more than two types of muscles to rotate.

How many muscles and articulations should coordinate in movements? A very simple task, holding a cup and drinking the coffee in it, for example, will require the coordination within tens of articulations and muscles.

It is inappropriate to consider the mind as a 'control tower' which dominates the body movements. Body is too complex to be controlled by the mind.

Of course the body moves in accordance with our intention. But this does not mean the mind 'controls' the body. The body must have its own way to coordinate hundreds of articulations and muscles.

But how?
