So you agree then that the tightening of the vocal cords cannot be achieved as efficiently when the laryngeal nerves have been damaged!
This is true. No one has disputed this. In fact, this can be brought up as a refutation of your claims. The longer a nerve is, the easier it is to damage. The easier it is to damage, the more likely it is to impact the sending of signals. I guess the long nerve is a bad idea.
You are therefore suggesting that the normal laryngeal nerve is constantly sending signals to tighten the muscles? This means that the nerve and muscles would be in a constant state of overwork which would be grossly inefficient. If tension in the nerve and muscles was inbuilt then the nerve and muscles could remain relaxed and ready for vocalization at a moments notice.
Ok, serious question here: is English not your first language? The paragraph above doesn't make a whole lot of sense. Either you don't speak English very well, or you are woefully uninformed on the workings of muscles and nerves. Or both.
