Brain And Muscle Power 大脑和肌肉力量 Muscles do not work by themselves. They depend on the brain' s neurons to tell muscles what to do. For example, if you want to move your little finger, a chain of electrical and chemical events must occur in order for your finger to move.肌肉不能自主控制,它们依赖大脑的神经元告诉它们该做什么。比如,如果你想要移动你的小手指,则会产生一系列的电、化学反应来使这一动作完成。
