The textbook view that projections of the arachnoid membrane into the cranial venous sinuses represent the primary cerebrospinal fluid (CSF) absorption sites seems incompatible with many clinical and experimental observations. On balance, there is more quantitative evidence suggesting a function for extracranial lymphatic vessels than exists to support a role for arachnoid villi and granulations in CSF transport.
教科书观点认为蛛网膜向颅静脉窦的投影代表主要的脑脊液（CSF）吸收部位，这似乎与许多临床和实验观察结果不符。权衡之下，有更多定量证据表明颅外淋巴管具有一定功能，而支持蛛网膜绒毛和颗粒在脑脊液运输中发挥作用的证据则较少。
