The presence in the left aortic nerve of rabbits of medullated and nonmedullated fibres with conduction velocities of 12--30 m/s and 0.9--1.2 m/s, respectively, was demonstrated. In experiments on the isolated aortic arch preparation the electrophysiological characteristics of the aortic baroceptors with the medullated and non-medullated fibres were studied by means of a selective block of conduction in these fibers. Baroceptors with the non-medullated fibers had a higher threshold pressure and a wider functional range.
已证实家兔左主动脉神经中存在有髓纤维和无髓纤维，其传导速度分别为12 - 30米/秒和0.9 - 1.2米/秒。在离体主动脉弓标本实验中，通过选择性阻断这些纤维的传导，研究了有髓纤维和无髓纤维的主动脉压力感受器的电生理特性。无髓纤维的压力感受器具有较高的阈值压力和较宽的功能范围。
