人类肩关节和髋关节关节唇发生学研究

Research on Aricular Labrum of Shoulder Joint and Hip Joint of Embryo

采用解剖学和组织学的研究方法 ,对胎儿期肩关节和髋关节的关节唇进行了观察 ,得到了有关胎儿时期这两大关节的关节唇的发生时间、形态学和组织学结构特征的材料 :1 肉眼可见的关节唇成型于胎儿 3个月 ,与胎儿关节的发生同步 .2 胎儿关节唇发生时为透明软骨 ,但是随着胎龄增加有向纤维软骨转化的趋势 .3 胎儿关节唇软骨中有血管存在 ,但血管的数量随胎龄增加而减少 .

The shape and structure of the articular labrum of fetus’ shoulder joint and hip joint are observed and researched and some information about the time when it happened and morphological characteristics are obtained.1. When the fetus is three months old,articular labrum can be seen by naked eyes,which is synchronous development with joints.2. The articular labrum of the shoulder joint and hip joint is a hyaline cartila.3. The number of the blood vessels in the fibrocartilage will decrease with the age of the fetus.
