영문 초록

We removed the CMJ region of NewZealand Rabbit, and 8㎛-depth sections on the sagital plane and the serial coronal planes were prepared as usual sequence for light microscopic study. They were stained with Hematoxylin Eosin or Masson s Triohrome staining and were observed under the light microscope. The results obtained were as follows: 1. Most parts of the CMJ disc was composed of collagen fibrils and myofibrils. The collagen fibrils and myofibrils forms coarse bundles in the crimped pattern and they were oriented predominantly in an anterior-posterior direction and were flared out into the posterior band areas. 2. The anterior band of the CMJ disc was attached to the anterior margin of the condyle inferiorly and the articular eminence of squamosal bone superiorly. The posterior band runs along the nonarticular surface of the condyle head posteriorly and then disappeared. So it is suggested that the rabbit CMJ disc be made of fibrous cartilage and the coarse bundles of myofibrils, which make the rabbit CMJ disc more visco-elastic and reinforced against external pressure and allow controlled gliding of the disc-condyle complex.
