| 摘要: |
| 本研究应用 HRP 追踪法对20例北京鸭各心区交感节后神经元进行定位。标记细胞多位于颈16(C15、胸1～2(T1-2)交感神经节(峰值在 T1节,约占61%),偶见于颈15(C15）和胸3(T3)交感神经节;呈双侧性;以同侧略占优势。标标细胞为多突起的星形运动神经元,以中小型(φ≤29μm)为主(占97%);在交感神经节内,大部分位于节的下角端部。支配心脏各区的交感节后神经元胞体在交感神经节内的位置没有差异,但两侧心交感神经分布不对称。 |

| Abstract: |
| This paper has dealt with the localization of the cardiac sympa- thetic postganglionic neurons in the Pekin duck was investigated using the retrograde transport of HRP.The solution of HRP were injected into specific regions of the heart in 20 ducks.The labeled cells were found in the sympathe- tic ganglia of C16-T2.They mainly in T1(about 61%).It was bilateral with slight- ly heavier labeling found ipsilateral to the injecting site than contralateral to it.Most of the labeled cells were multipolar,and ... |
