The microtubules in the neurosecretory neurones of the posterior pituitary were studied using different electron microscopical techniques. Tannic acid staining indicated that the microtubules had a 13 protofilament substructure similar to that described for microtubules from other tissues and organisms; the dimensions of the microtubules were also similar to that previously reported. Albumen pretreatment clearly showed the microtubules running across axonal swellings, but not continuing across the nerve endings. The only organelles showing possible association with the microtubules were small vesicles and smooth endoplasmic reticulum, no association between hormone granules and microtubules could be seen.
利用不同的电子显微镜技术对垂体后叶神经分泌神经元中的微管进行了研究。单宁酸染色表明，微管具有13条原纤维的亚结构，与其他组织和生物体中的微管所描述的结构相似；微管的尺寸也与先前报道的相似。白蛋白预处理清楚地显示微管穿过轴突肿胀处，但没有延伸穿过神经末梢。唯一显示可能与微管相关的细胞器是小泡和平滑内质网，未观察到激素颗粒与微管之间的关联。
