Examination of the synaptic membranes in calyciform endings of the chick ciliary ganglion has shown tight junctions selectively located on axon hillocks of postsynaptic neurons. Observations of similar membrane fusion in other junctions that involve electrotonic transmission suggest the possibility of identifying electrotonic junctions by electron microscopy.
对鸡睫状神经节杯状末梢中突触膜的检查显示，紧密连接选择性地位于突触后神经元的轴丘上。在其他涉及电紧张性传递的连接处观察到类似的膜融合现象，这表明通过电子显微镜识别电紧张性连接的可能性。
