本文报道了对胸中间外侧核（节前交感神经元柱）内神经元成分的高尔基体研究，以及一些附加的电镜观察结果。交感神经元的树突是严格纵向定向的，其轴突可沿腹角和侧索之间的边界沿着直接追踪到腹根。没有最初的轴突侧支可以观察到。中间外侧核的神经元群体是完全均匀的，很少被其他细胞的树突污染。该核的轴突神经元也是纵向定向的，并且主要由外侧索的侧支供给。轴突和树突分支之间的突触排列主要是“攀爬型”。在电子显微镜照片中可以识别出三种不同类型的突触终末：（1）含有异常大量的大嗜锇小泡和明显透明的普通小泡的终末;（2）含有特征性扁平小泡的终末（通常为轴-体）;（3）含有透明球形突触小泡的轴-树突终末。
A Golgi study of the neuronal elements in the thoracic intermedio-lateral nucleus (preganglionic sympathetic neuronal column) is presented, with some additional electron microscopic observations.The dendrites of the sympathetic neurons are strictly longitudinally oriented; their axons can be traced along the border between the ventral horn and the lateral funiculus directly into the ventral rootlers. No initial collateral of the axons can be observed. The neuronal population of the intermedio-lateral nucleus is entirely homogeneous and little contaminated by dendrites of other cells. The axonal neuropil of the nucleus is also longitudinally oriented and is fed mainly from collaterals of the lateral funiculus. The synaptic arrangement between the axonal and dendritic arborizations is mainly of the ‘climbing type’. Three different kinds of synaptic terminals can be recognized in the electron microscope picture: (1) terminals containing an unusually large number of large osmiophilic vesicles and apparently clear ordinary vesicles; (2) terminals (often axo-somatic) containing characteristic flattened vesicles; and (3) axo-dendritic terminals containing clear spherical synaptic vesicles.
