Objective: To study morphological structure ofcartilagecanalsof epiphysis .
目的:研究骨骺软骨管的形态结构。
2
It was concluded that the cartilagecanalsof fetus play great roles in formation of secondary ossification center and exist in primary secondary ossification center.
说明胎儿股骨远端次级骨化中心初始时其内存在软骨管,软骨管对次级骨化中心的形成起作用。

To observe the correlativity between secondary ossification center and cartilagecanals in cartilage epiphysis and the initial morphosis of the secondary ossification center.
