1) sympathetic preganglionic fibers
交感节前神经纤维
2) preganglionic neurofibers
节前神经纤维
3) sympathetic preganglionic neuron
交感节前神经元
1.
By means of intracellular recordings from spinal cord slices of neonatal rats in vitro,the effects of 5-hydroxytryptamine (5-HT), nor-adrenaline (NA) and adrenaline (AD)on membrane potential in sympathetic preganglionic neurons (SPN) were observed,in order to clarify whether these neuron contain a single type of the monoamine receptor or in cornbination with more than one type of receptors.
应用新生大鼠离体脊髓薄片的细胞内记录，观察了5-羟色胺（5-HT）、去甲肾上腺素（NA）及肾上腺素（AD）对交感节前神经元（SPN）膜电位的作用，以期阐明三种单胶受体是共存于同一细胞，还是分别存在于不同细胞？实验结果显示：（1）5－HT，NA及AD分别使57。
2.
Intracellular recordings of antidromically indentified sympathetic preganglionic neurons(SPNs) were made in thoracolumbar spinal cord slices from neonate rats (7-16 days).
在新生大鼠胸腰段脊髓薄片，对经腹根逆行刺激鉴定的交感节前神经元（ＳＰＮｓ）进行细胞内记录。
4) prevertebral ganglia
椎前交感神经节

节前纤维
preganglionic fiber
由胞体位于脑干和脊髓中枢的自主神经节前神经元所发出的，需要在周围部自主神经节换元的轴突称为节前纤维，较细，有髓鞘。
