| 摘要: |
| 将HRP注入食管两侧壁,在两侧结状节出现大量的标记细胞。在颈1—8和胸1—6脊神经节中出现标记细胞,以颈2—6和胸1—3节中标记细胞较多,但标记细胞最多的节是颈6和胸2。脊神经节中的大、中标记细胞相对多于结状节。根据计数,结状节中标记细胞占总数的63.7％,而脊神经节占36.3％,即食管的感觉经由迷走神经传入占优势。 |

| Abstract: |
| Follow the injection of HRP into the walls of cervical esophagus, a large number of labelled cells were found in the bilateral nodose ganglia. Also ,labelled cells were found in the bilateral spinal ganglia from C1 to T6. The numbers of labelled cells in the C2-6 and T1-3 spinal ganglia were more than those in other ganglia, and labelled cells in C6 and T2 ganglia were the most numerous. The large-and medium-sized labelled cells in the spinal ganglia were relatively more than those in the nodose ganalia. By counting, the labelled cells in the nodose ganglia and those in the spinal ganglia accounted for 63.7% and 36.3% of the total respectively. This means that the afferent fibres innervating cervical esophagus are predominantly via the vagus nerve. |
