A morphometric analysis of 43 human maculae utriculi is presented. Individual data on the shape, total area and relative area of the pars interna are given. In addition, the sensitivity of the entire macula to shear stimuli in different directions was estimated. The mean area of 39 maculae from adults and children was 4.30 +/- 0.30 (SD) mm(2). The pars interna was slightly but significantly smaller than the pars externa. The interindividual variability was larger for the shape of the macula than for the total area and the percentage of the pars interna. The estimated responsiveness of the macula was largest for shear directed anteromedially and smallest for shear directed posteriorly. The data are discussed taking into consideration clinical findings on patients with unilateral loss of otolith function.
本文对43个人类椭圆囊斑进行了形态计量学分析。给出了关于内部部分的形状、总面积和相对面积的个体数据。此外，还估计了整个囊斑在不同方向上对剪切刺激的敏感性。来自成人和儿童的39个囊斑的平均面积为4.30±0.30（标准差）平方毫米。内部部分略小于外部部分，但差异显著。囊斑形状的个体间变异性大于总面积和内部部分的百分比。囊斑对剪切力的估计反应性在前内侧方向最大，在后侧方向最小。结合单侧耳石功能丧失患者的临床发现对这些数据进行了讨论。
