俗话说:十指连心。人类的手指蕴涵着人身的许多秘密。在人体的器官中.最精巧的部分就是手部的19块肌肉,也是手最宝贵的部分。因为有了它们,人才有了对掌和对指的功能,才可以做非常精巧、细致的活儿。手还是人类神经感觉最丰富,最敏感的部分,神经纤维也最集中。从比较学研究的角度来看,人类基因组的检测结果显示,人手上有100万根神经纤维,这是任何其他动物都无法比拟的。人也因此具备了最复杂、最特殊的功能——手和脑的联系与互动。
As the saying goes: ten fingers even heart. Human fingers contain many secrets of the human body.
