Abstract: Transmission electron microscope has been used to observe the glycogen body, the major marginal nuclei, the ventral margins of the lumbosacral cord and the lower coccygeal cord of chickens in which large amounts of glycogen accumulate. The typical glycogen body cells are located in the classically described glycogen body. They have a dense, irregular-shaped nucleus and also a dense juxtanuclear cytoplasm containing numerous free ribosomes, and a rather long cisternae of the rough endoplasmic reticulum, as well as Golgi apparatus and mitochondria. Their cytoplasm is almost completely occupied by large masses of sharply delimited glycogen. The glycogen body cells in the cervical and thoracic cords have a round, light nucleus and a light cytoplasm containing the usual component of organelles. The interface between the glycogen areas and the juxtanuclear regions in more obscure than in the typical glycogen body cells. The glycogen containing cells located in the ventral margins and in the major marginal nuclei of the lumbosacral cord belong to the same structures as the typical or the other glycogen body cells. The cell structures of the above-mentioned glycogen containing cells seem to show a gradual transition according to glycogen content per cell. The glycogen containing cells located in the lower coccygeal cord are found throughout the entire areas of the cord. They contain a round nucleus and have a low electron density. The prominent cytoplasmic component of this cell is the numerous gliofilaments ; these may be considered as fibrous astrocytes.
