【摘要】 用HRP法研究了猪左心室外侧壁的交感神经节后神经元的分布,结果表明:标记细胞位于左侧颈中神经节、右侧椎神经节、双侧颈胸神经节及第二至第四胸交感神经节。标记细胞以颈胸节最多,占59.4％。左侧出现的标记细胞数明显多于右侧。标记细胞为多突起的星形运动神经元,以直径20～30μ为主,占67％。颈胸神经节内的标记细胞,大部分位于节的前腹侧部。颈前神经节内未发现标记细胞。更多还原

【Abstract】 Localization of the sympathetic postganglionic neurons of the lateral wall of the left ventricle of heart in pigs was studied with the horseradish peroxidase ( HRP ) technique.The results are as follows: ( 1 ) the labeled cells were found in the left middle cervical ganglion, right vertebral ganglion, bilateral cervicothoracic ganglions ( BCTG ) and the 2nd-4th thoracic sympathetic ganglions, ( 2 ) the labeled cells were most in BCTG (59.4% ) s ( 3 ) the labeled cells on the left were more than those on the right, ( 4 ) the labeled cells were stellate motoneurons with several processes and most of them ( 67% ) were 20-30 um in diameter; ( 5 ) the labeled cells in BCTG occupied mostly cranial Ventral part of the ganglion; ( 6 ) no labeled cell was found in cranial cervical ganglion.更多还原
