Abstract

Water is essential for life. It is needed not only to survive but also to sustain daily life activities. The maintenance of daily life activities related to hygiene as well as prevention of epidemic diseases and accidents involving fire was as important in the past as today. Powerful empires built many open-air and covered cisterns for water reservation and constructed aqueducts to bring water from hinterland to these cisterns. The first prototypes of cisterns were constructed in the Neolithic age. Byzantine cisterns such as the Basilica Cistern and Aqueduct of Valens are excellent examples that are remnants from the past to present. Similar to these social measures for water preservation, biological structures exhibit their own measures. In the human body, subarachnoid cisterns of central nervous system are the best-known cisterns, despite the presence of the cisterna chyli and Golgi body. The central nervous system produces and stores water in the form of cerebrospinal fluid in the subarachnoid cisterns for mechanical and immunological protection of the anatomical structures and for autoregulation of cerebral blood flow every day. Any condition that may adversely affect the cisterns, public or subarachnoid, may cause serious ...Continue Reading
