utricle saccule

基本解释

Vestibule hair cells were normal at macula of saccule, macula of utricle and ampullary crest vestibule among C57BL/10J mice of varied age.
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。
Though we could not identify the basal membrane and sensory epithelia under micro-endoscopy, the utricle and saccule could be clearly identified.
微窥镜下分辨不出基底膜或听神经细胞的形态结构，可见畸形前庭的球囊、椭圆囊的囊性结构；
The shapes of utricle, saccule and crista ampullaris tended to mature at E15, and the shapes of supporting and hair cells also tended to mature. The vestibular organ was mature at P0.
到胚胎第15天，椭圆囊、球囊、壶腹峪初具成熟形态，毛细胞和支持细胞也初具雏形，到出生时，前庭器官已基本发育成熟。
