支配猪左心室侧壁的交感神经节后神经元的定位

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。

LOCALIZATION OF SYMPATHETIC POSTGANG-LIONIC NEURONS INNERVATING LATERAL WALL OF LEFT VENTRICLE OF HEART IN PIGS

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.
