Encapsulated sensory corpuscles of the Krause type were found in the mucosa of surgically removed human vocal cords. The corpuscles were ellipsoidal structures of about 30 to 50 micrometers and were located beneath the free edge in the mid-region along the intermembranous part. They contained a number of varicose nerve endings and lamellar cells. The lamellar cells had thin cytoplasmic lamellae which contained numerous cytoplasmic filaments and were interposed between the nerve endings. Attachment devices were frequently noted between the cytoplasmic lamellae and between the lamellae and nerve endings. Half-desmosomes were also noted along the plasma membrane of the lamellar cells. The intercellular space was filled with amorphous electron lucent material and contained a few collagen fibrils. Ladder-like filamentous structures were frequently encountered in the intercellular space. The location of the corpuscles at the free edge of the vocal cords suggests that the endings may receive the bilateral touch of the vibrating part of the cords in order to give sensory information for the control of the movement of the cords in phonation.
在手术切除的人体声带黏膜中发现了克劳泽型被囊感觉小体。这些小体为椭圆形结构，长约30至50微米，位于膜间部中部的游离缘下方。它们包含许多曲张神经末梢和板层细胞。板层细胞具有薄的细胞质板层，其中含有许多细胞质细丝，并夹在神经末梢之间。在细胞质板层之间以及板层与神经末梢之间经常可见附着装置。在板层细胞的质膜上也观察到半桥粒。细胞间隙充满无定形电子透明物质，并含有一些胶原纤维。在细胞间隙中经常遇到梯状丝状结构。小体位于声带游离缘的位置表明，这些末梢可能接收声带振动部分的双侧触觉，以便为发声时声带运动的控制提供感觉信息。
