啄木鸟不断地用喙啄树。但是，这种行为不会造成脑损伤或脑震荡。人不可能在不损害大脑的情况下强烈地打击头部。因此，可以预测啄木鸟的大脑通过一些方法来保护免受电击，啄木鸟具有吸收电击的原始机制。本研究对啄木鸟的内部结构，特别是头部结构进行了解剖，并对啄木鸟的防撞击系统进行了有限元分析和模型试验。结果表明，啄木鸟的舌骨、头骨、组织和脑等结构具有独特的形态，具有原始的抗冲击系统。并认为啄木鸟不仅头部具有先进的抗冲击系统，而且全身都具有先进的抗冲击系统。
A woodpecker strikes its beak toward a tree repeatedly. But, the damage of brain or the brain concussion doesn't occur by this action. Human cannot strike strongly the head without the damage of a brain. Therefore, it is predicted that the brain of a woodpecker is protected from the shock by some methods and that the woodpecker has the original mechanism to absorb a shock. In this study, the endoskeltal structure, especially head part structure of woodpecker is dissected and the impact-proof system is analyzed by FEM and model experiment. From the results, it is obvious that the woodpecker has the original impact-proof system as the unique states of hyoid bone, skull, tissue and brain. Moreover it is considered that woodpecker has the advanced impact-proof system relating with not only the head part but also with the whole body.
