The morphological similarity of the lining of arachnoid cysts to subdural neurothelium and the mesothelium of arachnoid granulations suggested that the latter tissues might be the origin of arachnoid cysts. Transport Na+-K+-adenosine triphosphatase was shown by enzyme ultracytochemistry to be an indication of secretory activity in the lining of arachnoid cysts and in the endothelial lining of arachnoid granulations. This secretory activity suggests the existence of a biochemical mechanism for cerebrospinal fluid absorption at these granulations separate from the mechanisms already demonstrated.
蛛网膜囊肿的内衬与硬脑膜下神经上皮及蛛网膜颗粒的间皮在形态学上的相似性表明，后两者组织可能是蛛网膜囊肿的起源。通过酶超微细胞化学显示，钠钾三磷酸腺苷酶的转运是蛛网膜囊肿内衬及蛛网膜颗粒内皮衬里分泌活动的一个指标。这种分泌活动表明，在这些颗粒处存在一种独立于已证实机制的脑脊液吸收生化机制。
