家兔膝关节软骨扫描电镜观察

Observation of the Knee Joint Cartilage of Rabbits Under the Scanning Electron Microscope

半月板下面,股骨髁关节面中间带、胫骨髁上关节面及半月板上面中环带,结构相似。即呈现团粒和由团粒结成的絮网状结构。股骨髁关节面两侧带、胫骨髁上关节面及半月板上面外环带,软骨表面团拉消失,移行为波状曲嵴。髌、股关节面的中间带,均为由较大团粒构成的复层结构。两侧带呈现波状曲髌。

DIGEST:The inferior surfaces of the menisci,the intermediate stripeof the articular surface of the femoral condyles,the supeior articularsurface of the tibial condyles and the intermediate clitella of the mensci,the yare similar in structure,which show the structure consisting ofgranulesand that of catkin-like network of granules.Instead of the granules structure of the cartilage surface there areundulatory ridges at both lateral stripes of the articular surface of thefemoral coadyles,the superior articular surface of the tibial condyles,and the lateral clitella of the superior surfaces of the menisci.The intermediate clitella of both patella and femur are covered withastratified structure of bigger granules,and both lateral stripes of themshows undulatory ridges.
