Laterality of sympathetic control of the diameter of the femoral artery (using an inductive transformer) and the blood flow in its consecutive bed (using a Stattham flowmeter) was studied at the postganglionic level. The fibres leaving LG3, LG4 and LG5 were stimulated. Stimulation of the left sympathetic trunk (ST) evoked 88.33 +/- 0.98% of maximum sympathetic constriction of the ipsilateral and 15.0 +/- 1.1% of the contralateral femoral artery (P less than 0.001). Stimulation of the right ST evoked 86.38 +/- 0.90% of maximum constriction of the ipsilateral and 11.95 +/- 0.99% of the contralateral femoral artery (P less than 0..001). Vasomotor fibres contained in the femoral nerve exert only 23.5 +/- 3.3% (P less than 0.01), while fibres from other sources (probably including the aortic plexus) were responsible for 74.1 +/- 5.2% (P less than 0.001) of maximum constriction. The blood flow in the resistant bed consecutive to the left and right femoral artery is controlled solely by postganglionic fibres of the ipsilateral lumbar ganglia. The results indicate the variability of lateralization of the sympathetic control of the individual segments of the vascular tree.
在节后水平研究了交感神经对股动脉直径（使用感应变压器）及其连续床层血流（使用斯塔瑟姆流量计）的控制的偏向性。刺激离开LG3、LG4和LG5的纤维。刺激左侧交感干（ST）引起同侧股动脉最大交感收缩的88.33±0.98%，对侧股动脉的15.0±1.1%（P＜0.001）。刺激右侧ST引起同侧股动脉最大收缩的86.38±0.90%，对侧股动脉的11.95±0.99%（P＜0.001）。股神经中含有的血管运动纤维仅产生23.5±3.3%（P＜0.01），而来自其他来源（可能包括主动脉丛）的纤维负责最大收缩的74.1±5.2%（P＜0.001）。与左、右股动脉连续的阻力床层中的血流仅由同侧腰神经节的节后纤维控制。结果表明血管树各节段交感神经控制的偏向性存在变异性。
