Geometrical features of electron microgram profiles of presynaptic terminals (PTs) in the dorsal horn of the cat spinal cord were studied. The statistical approach which has permitted estimating the surface area of the closed membrane on the basis of parameters of its plane random sections is described. Mean surface area of the plasma membrane of observed PTs is estimated. The probability estimate of the mean number of active zones per each presynaptic bouton is considered. The obtained quantitative data are discussed for the possibility to describe physical processes occurring in presynapses.
对猫脊髓背角中突触前终末（PTs）的电子显微镜图像轮廓的几何特征进行了研究。描述了一种基于平面随机截面参数来估计封闭膜表面积的统计方法。估计了观察到的PTs质膜的平均表面积。考虑了每个突触前小体活性区平均数量的概率估计。讨论了所获得的定量数据用于描述突触前发生的物理过程的可能性。
