Fine structural features of pinealocytes of cotton rats (Sigmodon hispidus) were examined. Golgi complexes, mitochondria, endoplasmic reticulum and polysomes are usual organelles seen in the perikaryonal cytoplasm of pinealocytes. Many non-granulated vesicles (40 to 80 nm in diameter) and a few granulated vesicles (about 100 nm in diameter) are associated with the Golgi cisternae. Occasionally, the cisternae contain granular materials. The perikaryonal cytoplasm of pinealocytes is characterized by the presence of inclusion bodies. These bodies are usually round in shape, not bounded by a limiting membrane and composed of fine granular or filamentous materials of high electron-opacity, which are similar in appearance to the substance seen in the nucleolonema. Pinealocyte processes, filled with abundant non-granulated vesicles and some granulated vesicles, are mainly found within the parenchyma and occasionally in perivascular spaces.
对棉鼠（棉鼠属）松果体细胞的精细结构特征进行了检查。高尔基体、线粒体、内质网和多核糖体是松果体细胞核周细胞质中常见的细胞器。许多无颗粒小泡（直径40至80纳米）和一些有颗粒小泡（直径约100纳米）与高尔基池相关联。偶尔，池内含有颗粒物质。松果体细胞的核周细胞质以存在包涵体为特征。这些体通常呈圆形，无界膜，由高电子密度的细颗粒或丝状物质组成，其外观与核仁线中所见物质相似。充满大量无颗粒小泡和一些有颗粒小泡的松果体细胞突起主要见于实质内，偶尔见于血管周围间隙。
