The saccus vasculosus (SV) of C. batrachus is comparatively small and situated latero-dorsal to the pituitary in between the lobi inferiores. It is in open communication with the third ventricle and is made up of coronet and supporting glial cells with interspersed liquor contacting neurons. These cellular constituents are arranged in one to three layers which are not thrown into folds. The PAS positive nature of the apical part of some coronet cells and their continuation with the PAS and AF positive material present in the lumen strongly suggest their secretory role. The coronet cells exhibited strong NADH diaphorase, NADPH diaphorase, cytochrome oxidase and MAO activity. AChE activity was comparatively weak. These enzyme histochemical studies show that SV has a dual function of transport and secretion. The strong MAO activity suggests the probable aminergic control of this organ.
牛蛙的血管囊相对较小，位于垂体的后外侧，在左右下叶之间。它与第三脑室相通，由冠状细胞和支持性神经胶质细胞组成，其间散布着与脑脊液接触的神经元。这些细胞成分排列成一至三层，没有形成褶皱。一些冠状细胞顶端部分的PAS阳性特性以及它们与管腔内PAS和AF阳性物质的延续性，强烈表明它们具有分泌作用。冠状细胞表现出强烈的NADH黄递酶、NADPH黄递酶、细胞色素氧化酶和MAO活性。乙酰胆碱酯酶活性相对较弱。这些酶组织化学研究表明，血管囊具有运输和分泌的双重功能。强烈的MAO活性表明该器官可能受胺能控制。
