The innervation of skeletal muscle by the lumbar sympathetic nerve was studied through the glyoxic acid histochemical method and the horseradish peroxidase method on 16 anesthesized rabbits. Blood flow changes in the quadriceps muscles during and after stimulation of the sympathetic nerves were evaluated by the heated thermocouple technique in 12 anesthesized rabbits. It seems likely that the postganglionic nerve fibers join to the spinal nerve at the intervertebral foramen and run into the peripheral nerves. The vastus medialis and rectus femoris were mainly innervated by the sympathetic neurons at different segmental levels. Sympathetic disturbance at the segmental level may occur when the spinal nerve is disturbed at the intervertebral foramen. Muscle blood flow decreased after sympathetic nerve stimulation for 1 minute. However, an increase took place after stimulation for 5 minutes. These results suggest the presence of some neurotransmitter present in the postganglionic nerve terminals.
通过对16只麻醉兔采用乙醛酸组织化学法和辣根过氧化物酶法，研究了腰交感神经对骨骼肌的神经支配。采用热偶技术对12只麻醉兔在刺激交感神经期间及之后股四头肌的血流变化进行了评估。节后神经纤维似乎在椎间孔处与脊神经相连并进入外周神经。股内侧肌和股直肌主要由不同节段水平的交感神经元支配。当脊神经在椎间孔处受到干扰时，可能会发生节段水平的交感神经紊乱。交感神经刺激1分钟后肌肉血流减少。然而，刺激5分钟后血流增加。这些结果提示节后神经末梢存在某种神经递质。
