Using a new histometric method, the orientation of primary osteons was measured in the main long bones of adult mallards (Anas platyrhynchos). In the light of previous biomechanical and ontogenetic studies, a functional hypothesis is proposed, explaining the histological differences observed between long bones; laminar bone tissue, mainly found in the wing bones, may be a biomechanical adaptation to torsional loads caused by flapping flight.
采用一种新的组织测量方法,对成年绿头鸭(Anas platyrhynchos)主要长骨中初级骨单位的方向进行了测量。根据先前的生物力学和个体发育研究,提出了一个功能假说,用以解释长骨之间观察到的组织学差异;主要存在于翼骨中的层状骨组织,可能是对扑翼飞行引起的扭转载荷的一种生物力学适应。
