1·Conclusions: Delayed reimplantation of avulsion ventral root can enhance motoneuron survival and regeneration.

结论：前根撕脱延期再植回能促进脊髓前角运动神经元的存活与再生。

2·The periodic discharge activity was recorded from ventral root c4 or c5 and the neurons of medulla of the preparation.

在此标本上记录到了颈4,5脊神经腹根及延髓神经元的节律性放电活动。

3·This fact shows that some ventral root cells might give their central processes to enter the spinal cord via dorsal roots.

这一事实说明前根细胞的中枢突，也有经后根入脊髓的。

4·Objective: the morphological correlation between the ventral nerve root and the dorsal nerve root ganglion of the spinal nerve was analyzed in order to offer basis for nerve root infiltration.

目的：了解腰骶神经前根、后根、后根神经节位置关系及其变异，为下腰椎神经根造影提供解剖学依据。
