A software using a finite element method is used to study the deformation of a bidimensional model of the human cupular diaphragm and the distribution of angular shearing of the hairs of the sensory cells located on the crista ampularis. This study shows that the hairs on the top of the crista are more sensitive to the pressure difference across the cupula due to angular acceleration of the head and those located on the sides of the crista are sensitive to the variation of the inflation pressure of the ampulla. This spatial discrimination of sensibility of the hair cells to the two types of mechanical solicitations leads us to consider the SCC as regulated sensor.
使用有限元方法的软件用于研究人椭圆囊斑二维模型的变形以及位于壶腹嵴上的感觉细胞纤毛的角剪切分布。该研究表明，由于头部角加速度，壶腹嵴顶部的纤毛对椭圆囊两侧的压力差更敏感，而位于壶腹嵴侧面的纤毛对壶腹膨胀压力的变化敏感。毛细胞对这两种机械刺激的敏感性的这种空间辨别使我们将半规管视为受调节的传感器。
