Sažetak
Development of the glycogen body was investigated in turkey (Meleagris gallopavo) embryo. The glycogen body is formed by cells rich in glycogen. To date, neither the origin of these cells nor the function of the glycogen body have been entirely clarified. The glycogen body in turkey embryo develops from the paired primordia which appear in the dorsal part of the spinal cord on both sides of the ependymal septum on the 11th day of embryonic development. On the 12th day of development the number of cells increases and fusion of the paired primordia begin dorsally and is completed on the 14th day. On the 13th day of development the paired primordia of the ventral part of the glycogen body appear ventrolaterally from the central canal. In the further course of development they gradually enclose the central canal. The total development of the glycogen body in turkey is completed on the 25th day of development. The dorsal and ventral parts are joined and the central canal of the spinal cord lies within the glycogen body.
