It is fascinating to read and understand how muscles work. For all my life, (since I had not given it any thought earlier), I simply had assumed a muscle is 1 muscle. Ex, if we say bicep muscle, it was one muscle in my mind (I don't know why I imagined so, but so it was). The truth is very far from it . Each muscle is made up of hundreds of strands (maybe thousands). And the best part (I have practically understood, not backed by any medical stuff) - is that each strand is connected separately to the brain and not as one. For mechanical enthusiasts, each strand works like a sort of rack and pinion arrangement, operated by a chemical reaction, triggered by the brain. Each strand has two separate connections to the brain - one to work the rack and pinion arrangement each way (to contract the muscle strand and the other to release it or relax the muscle strand). In short, that's how it achieves any movement. By selecting the set of muscle strands to activate (how many most probab
