脊椎动物内耳中,悬系在骨迷路内的膜性囊管,形状和骨迷路相似。包括椭圆囊和球囊、膜半规管及耳蜗管。两个囊位于前庭中、膜半规管和耳蜗管位于骨迷路的同名部分内,形状也相同。管壁由单层上皮及薄层结缔组织构成。腔内充满内淋巴。膜迷路与骨迷膜间有外淋巴。内、外淋巴互不相通。椭圆囊与3个半规管相通联,球囊与椭圆囊和耳蜗管相通。膜迷路壁上有6个神经上皮增厚区,在两个囊壁上的称位觉斑,在3个膜半规管壶腹上的称壶腹嵴,在耳蜗管的称螺旋器。其中螺旋器司听觉,其余都是司平衡觉。
膜迷路(membranous labyrinth)是一系列的膜性管和囊,悬于骨迷路内。骨性半规管内有膜性半规管,前庭内有球囊和椭圆囊,耳蜗内有蜗管。

目的探讨实验性膜迷路积水前庭损害的机制。
Objective To explore the mechanism for the experimental vestibule damage in endolymphatic hydrops.
MRI对膜迷路出血、炎症、小听神经瘤以及脑干小腔隙灶的显示比CT更具优势。
MRI was obviously superior to CT in detecting membranous labyrinthine hemorrhage, inflammation, small acoustic tumors and tiny lacunar infarction in brain stem.
结论实验性膜迷路积水早期不影响前庭碳酸酐酶活性,提示实验性膜迷路积水早期对内淋巴液的产生无明显影响。
Conclusions It was suggested that the secretion of endolymphatic fluid was not affected at the early stage of the experimental endolymphatic hydrops.
