• secondary osteons - 引用次数：2

  Many secondary osteons are found in humerus or femur of some large birds such as Crossoptilon auritum,Tetraogallus himalayensis,Syrmaticus reevesii, Aegypius monachus,but not in small birds. The number of secondary osteons may relate to the capability of weight bearing in birds.

  一些大型鸟类如:蓝马鸡、暗腹雪鸡、白颈长尾雉、秃鹫等的肱骨或股骨的骨组织中发现有大量的次级骨单位,而在小型鸟类中这种现象很少见,说明次级骨单位与鸟类骨骼的承重能力的强弱有关。
