山羊腓神经感觉和运动神经元胞体的位置和形态——辣根过氧化物酶(HRP)法

Studies on The Origin And Segmental Distribution of Nervus Peronaeus in Goats——By Horseradish Peroxidase Method

用HRP法对七只山羊的腓神经的来源及节段性分布规律进行追踪观察,结果如下: 1.腓神经感觉神经元胞体主要集中于L_6和S_1脊神经节内,其次位于S_2脊神经节内。其胞体多呈椭圆形和圆形,可分大、中、小三型,而以中型为主。 2.腓神经运动神经元胞体主要集中于L_6和S_1脊髓腹角,其次位于L_S脊髓腹角。胞体多呈星状或三角形。多数为较大的多极神经元,少数为小型多极神经元。

The experiments were conducted, using 7 goats, to investigate the origin and distribution of the nervus peronaeus by means of horseradish peroxidase methodoOur observations are listed as follows: 1. The majority of the perikanyons of the sensory neurons of nervus peronaeus are located in the spinal ganglia from L_5 to S_1, and next in S_2. The most observed neurons are oval and round and can be divided into3types with the medium-sized neurons making up the majority. 2. The motor neurons of nervus peronaeus are largely located in the ventral horn of the spinal cord from L_6 to S_1. Some of them are distributed in the ventral horn of spinal cord L_5. The neurons are stellate and triangle in shape. And most of them are large multiple neurons, with a limited number of them being small-sized multiple neurons.
