Physiological Knowledge required, not Muscle-Knowledge:

In the past it has been attempted to help the student totally from the opposite side, that is by trying to instruct him as to the precise

2. nomenclature

of the musdes employed. This is even a more problematic method than the last, and is in fact not only futile, but likely to prove seriously harmful to the learner. The anatomical road, moreover, is impracticable, and useless (so far as learning and teaching are concerned) for the two following compelling and quite insurmountable reasons:

1. It is physiologically and psychologically impossible for us directly to provoke or prompt any particular musclue into activity by any act of thinking of it, or wishing or willing it, no matter how concentrated our effort. Musles can only be provoked into action indirectly, by our willing a particular limb-exertion or movement.
2. The muscular processes needed for many quite simple actions are so complex as to be practically unthinkable, even if we could separately prompt the required musdes into action which we cannot do.

Is it physiologically or psychologically possible for a human to directly provoke any particular muscle into activity by an act of thinking? Yes, it is possible for a human to directly provoke a particular muscle into activity by an act of thinking. This is known as "mind-muscle connection" or "neuromuscular control" and is a real phenomenon that has been studied in the field of sports science. The mind-muscle connection refers to the ability to consciously activate and control specific muscles through focused attention and visualization. This technique is commonly used by athletes and bodybuilders to improve their performance and develop specific muscles. Research has shown that when you focus your attention on a particular muscle, your brain activates the neurons that control that muscle, resulting in increased activation and recruitment of muscle fibers. By visualizing the muscle contracting and relaxing, you can further enhance the mind-muscle connection and improve your ability to control that muscle. However, it is important to note that the mind-muscle connection may not work for everyone and may require practice and training to develop. Additionally, certain factors such as injury, pain, and neurological conditions may affect a person's ability to activate and control specific muscles.
