Abstract
The development and change of the cartilage canals ralated to chondrocyte growth and the major histological pattern were investigated in the calcaneus of the Korean native cattle fetuses from CRL 28mm to 175mm. The results as follows; 1. The cartilage canal first appeared in the caudal subperichondral region of the sustentaculum tali of the CRL 28mm fetus, and well developed after the period. 2. The three major cartilage canals, one entered from the head of calcaneous into where achilles tendon insert and the others from the caudal region of sustentaculum tali and the calcaneal sulcus, growth distinctively. The latters participated in the ossification center prior to the former. 3. The number of cells in this canals and the size increased synchronously with chondrocytic hypertrophy. In the intermediate and deep canals, the chondrogenic change showed distinctinvely. Our results demonstrated that the cartilage canals from the lower part were important the formation of the ossification center, and the growth and development of canals associated with the hypertropic changes of chondrocytes in the calcaneus of the Korean native cattle fetus.
