The pineal system of the Mongolian gerbil (Meriones unguiculatus) was investigated by light and electron microscopy, special attention being paid to the sites of contact with the ventricular system. The results reveal that the pineal system of this species has a specific topographical relationship to the suprapineal recess of the third ventricle. The dorsal side of the proximal part of the pineal system forms the floor and the caudal wall of this recess. Here, a consistent and relatively large area lacks an ependymal lining, enabling pinealocytes to come into direct contact with the cerebrospinal fluid (CSF). This area is assumed to be the morphological correlate of a close functional interrelationship between the pineal tissue and the CSF.
通过光学显微镜和电子显微镜对长爪沙鼠（Meriones unguiculatus）的松果体系统进行了研究，特别关注了与脑室系统的接触部位。结果显示，该物种的松果体系统与第三脑室松果体上隐窝具有特定的拓扑关系。松果体系统近端部分的背侧构成了该隐窝的底部和尾壁。在这里，有一片持续且相对较大的区域缺乏室管膜衬里，使得松果体细胞能够直接与脑脊液（CSF）接触。该区域被认为是松果体组织与脑脊液之间紧密功能相互关系的形态学关联。
