在人类胎儿中，瓣膜是由柱状上皮内衬的高度细胞化的结缔组织瓣。它保护椭圆囊开口进入髓内管。瓣膜是椭圆囊和内淋巴管的后壁在交界处的褶皱。这种阀状结构的功能尚未确定。它的位置表明内淋巴的流动是从内淋巴管到椭圆囊，但这不是一个必要的结论。如果流动是在另一个方向，淋巴的缓慢运动可能不会影响这个阀门。然而，在突然的压力扰动的情况下，该阀可以防止内淋巴从椭圆囊流出，从而在椭圆囊和半规管内保持更恒定的压力。
In the human fetus the valve is a highly cellular connective tissue flap lined by columnar epithelium. It guards the utricular opening into the canalis endo-lymphaticus. The valve is a fold of the posterior wall of the utricle and endolymphatic canal at the point of junction. Function of this valve-like structure has not been determined. Its position would indicate that the flow of endolymph is from the endolymphatic canal to the utricle, but this is not a necessary conclusion. If the flow is in the other direction, slow movement of the lymph may not affect this valve. However, in case of sudden pressure disturbance, this valve may prevent the outflow of endolymph from the utricle, thus maintaining a more constant pressure within the utricle and semicircular canals.
