Several types of giant neurons exist in the extrahepatic bile ducts in the dog. The intrinsic innervation of the ducts wall has the characteristics as follows: 1) within the nerve, fascicless axons and nerve terminals come into a different relation to the glial cytoplasm; 2) two categories of the nerve terminals are identified by their glial accompaniment--"closed" and "open" types; 3) separation of the nerve terminals containing synaptic vesicles from the several effector elements is usually about several thousand A and with no synapses; typical synaptic complexes were identified between nerve terminals and neurons, although not as commonly as would have been expected considering the large amount of nerve terminals surrounding some of the neurons; 4) within the interstitial space the terminals are often of the "open" type. The morphological data suggest that the peripheral vegetative fibers may form transitional provisional "functional" nerve endings.
犬肝外胆管中存在几种类型的巨型神经元。胆管壁的内在神经支配具有以下特点：1）在神经内，无束状轴突和神经末梢与神经胶质细胞质形成不同的关系；2）两类神经末梢通过其神经胶质伴随物得以识别——“封闭”型和“开放”型；3）含有突触小泡的神经末梢与几种效应器元件的分离通常约为数千埃且无突触；在神经末梢与神经元之间发现了典型的突触复合体，尽管考虑到某些神经元周围大量的神经末梢，其出现频率不如预期的高；4）在间隙空间内，末梢通常为“开放”型。形态学数据表明，外周植物性纤维可能形成过渡性临时“功能性”神经末梢。
