Summary Cartilage canals have been extensively investigated, in particular as to their mode of formation, morphologic distribution, function and fate. We studied the morphological pattern of the cartilage canals of the right upper chondroepiphysis of the tibia of chick embryos, Hamburger–Hamilton stages 35–42, in serial sagittal wax sections and in reconstructions made with AutoCAD software. The spatial arrangement of the canals is presented in a series of drawings made according to computerized images. The canals were penetrated from three distinct surfaces: the anterior and superior surfaces of the tubercle and the posterior surfaces of the medial and lateral condyles. Immediately after entering, nearly all the canals were extended toward the medial or lateral aspects of the chondroepiphysis, from which no canals took their origin. All of the cartilage canals connected with the perichondrium, and their branching did not follow a specific pattern. The condylar canals did not unite with the tubercular ones.
