• 中文摘要： 本實驗係將過氧化氫醇（HRP）注入貓單側頸上神經節（SCG），利用HRP逆向傳遞作用以追溯其傳入神經纖維之來源。結果顯示其有三種不同的來源：（1）同側C8－T5段脊髓的節前神經元集中在Tl－T3段，尤以Tl一T3段脊髓為多，且主要位在中間外側核（2）同側頸中和星狀神經節及對側頸上神經節。（3）三叉神經節下顎支部。由以上結果顯示頸上神經節除接受脊髓節前神經纖維外，尚可接受其他多處投射來的神經纖維，經複雜的聯會整合後，其節後神經纖維再支配頭頸部臟器。
• 英文摘要： The origins of the afferent fibers to the cat's superior cervical ganglion (SCG) were demonstratedby using the retrograde horseradish peroxidase tracing method. We found that the preganglionic neuronswere located in the spinal segments C8-T5, particularly in T1-T3. These neurons were situated mainlyin the intermediolateral column. The extra-SCG neurons along with the cervical sympathetic trunkoriginated ipsilaterally from the middle cervical and stellate ganglia, and contralaterally from the caudalpart of the SCG. Labeled neurons also originated from the mandibular division of the trigeminal ganglion.Our results demonstrated that many fiber sources projected to the SCG, which plays a complicated synapticrole in controlling the visceral organs of the head and neck region.
