半规管的壶腹嵴由一排感觉毛细胞和2～3排支持细胞构成。

The crista awpullaris of the semicircular canal consisted of a layer of sensory hair cells and2-3 layers of supporting cells .

台盼蓝染色法观察脉冲口噪声对豚鼠壶腹嵴毛细胞活力的损伤

The evaluation of the injury of pulse intense sound to the hair cell in ampullar crest of guinea pig by trypan blue staining

证明了内淋巴液对于半规管系统的整体动力学特性具有决定作用，而壶腹嵴则对于系统的最终稳态分布起决定作用。

It is proved that the endolymph fluid controls the global system response and the utricle controls the final response of the system .

目的：为了判断噪声损伤对豚鼠壶腹嵴感觉上皮损伤的程度。方法：对31只杂色豚鼠进行实验性脉冲噪声损伤，并对豚鼠壶腹嵴施行细胞分离，台盼蓝染色，观察毛细胞活力。

This study was undertaken to determine the injure of pulse intense sound to the hair cell in the ampullar cristae with trypan blue staining .

另外，壶腹嵴的形态学损害比球囊斑和椭园囊斑发生早而且更为严重。

In addition , the morphological damage occurred earlier and was more severe in the crista than in the maculae of the saccule and utricle .

前庭选取球囊斑，椭圆囊斑和壶腹嵴三个部位进行观察，不同月龄的C57BL/10J鼠前庭毛细胞均正常。

Vestibule hair cells were normal at macula of saccule , macula of utricle and ampullary crest vestibule among C57BL / 10J mice of varied age .

用透射电镜对11例10～37周胎儿壶腹嵴暗细胞进行观察。

The dark cells of crista ampullaris in 11 cases of human fetuses , from 10th week to 37th week , were observed by transmission electron microscope .

前庭感受器包括感受重力和直线变速运动的耳石器和感受角变速运动的壶腹嵴。

The vestibular receptors include the otoliths organ that recept the gravity and the liner accelerative motion , and the crista ampullaris which recept the information of the angle accelerative movement .

第30天前、后壶腹嵴基本发育成形；预定柯蒂氏器出现了柱状或瓶状毛细胞的分化。

At the 30th day of incubation , the anterior and posterior cristae had basically been formed , and the differentiation of pillar or bottle-shaped hair cells started on the presumptive basilar papilla .

壶腹嵴暗细胞区的黑色素细胞随暗细胞胞浆突起的发育而出现，说明二者关系密切。

Melanocytes in the area of crista ampullaris appeared with the development of the cytoplasmic processes of the dark cells . Therefore , it is reasonable to suggest that there is close relationship between the melanocytes and dark cells .

对照组壶腹嵴结构正常，照射组壶腹嵴与对照组相比，感觉上皮变薄，毛细胞数量减少，纤毛消失。

In irradiation group , the cilia of hair cells in macula utriculi became shorter , the number of cilia and hair cells decreased and the otolith disappeared . The structure of crista ampullaris of control group was normal .

壶腹帽的最大剪切应变集中在壶腹嵴嵴顶附近，EH时明显增加。

The maximum shear strain of cupula occurs near the top surface of the crista .
