The pineal gland is made up of plates of cells separated by septa. Two cell types are recognized by special techniques, the more common parenchymal cell and the neuroglial (astrocyte-like) supporting cell. The latter is found between clusters of parenchymal cells. The two cell types cannot be distinguished in ordinary H. & E. preparations. Concretions or brain sand characterize the pineal gland and increase with age. They have a mineralized organic matrix and, at high magnification, appear lamellated.
