This paper some characteristics of the appearance of cartilages canals in the fetal epiphyses. In the human fetus, the epiphysis are
large blocks of hyaline cartilage and the chondrocytes in the middle of the bone anlage cannot be nourrished by ssimple diffusion. Cartilage canals are specialized structures that bring vascular loops in the center of the epiphysis to vascularize it.
