Myelinated and non-myelinated nerve fibres follow the bronchi which share in the formation of the pericartilaginous plexus, posteriorly. Meso- and parabronchi were richely innervated by a large number of non-myelinated nerve fibres. Rounded ganglia (large and small) were observed near the wall of the bronchi and parabronchi. Large ganglia with numerous nerve cells were observed in the parenchymal tissue. Occasionally ganglia were seen in between parabronchial space and in the connective tissue space. Muscle were also richly innervated by non-myelinated nerve fibres and were marked in close associationship with the pre- and postganglionic nerve fibres of the perimuscular ganglia. The neural networks, formed by fine branches of non-myelinated nerve fibres, were either connected with the vascular (arterial) plexuses, neural terminal network, fibres of the pericartilaginous plexus or meso- and parabronchial plexus.
有髓神经纤维和无髓神经纤维沿着支气管走行，支气管在后方参与形成软骨膜周丛。中支气管和副支气管由大量无髓神经纤维丰富地支配。在支气管和副支气管壁附近观察到圆形神经节（大的和小的）。在实质组织中观察到含有大量神经细胞的大神经节。偶尔在副支气管间隙和结缔组织间隙中也可见神经节。肌肉也由无髓神经纤维丰富地支配，并与肌周神经节的节前和节后神经纤维紧密相连。由无髓神经纤维的细支形成的神经网络，要么与血管（动脉）丛、神经终末网络、软骨膜周丛的纤维或中支气管和副支气管丛相连。
