On impactproof systems studied from endoskeltal structure of woodpeckers

Abstract

A woodpecker strikes its beak toward a tree repeatedly. But, the damage of brain or the brain concussion don't occur by this action. Human cannot strike the head without the damage of a brain strongly. Therefore, Itis predicted that the brain of a woodpecker is protected from the shock by some methods and it turns out that the woodpecker has the original mechanism which absorbs a shock. In this study, the endoskeltal structure, especialy head part structure, of woodpecker is investigated by dissecting in a point of view of impactproof.
