脊神经前根

SD大鼠腰骶部脊神经前根显微外科解剖学观察

The microsurgical anatomy of the lumbosacral ventral roots in SD rat

结论：L1与L3脊神经前根吻合可成功建立L2脊髓半切损伤大鼠的股四头肌脊髓旁神经反射通路。

Conclusion : New paraspinal pathway of quadriceps femoris can be established by L1-L3 spinal ventral roots anastomosis after spinal cord injury at L2 level hemitransection in rats .

T11、T12前根出硬膜平面均高于S2～4脊神经前根出脊髓平面；

The level of T 11 , T 12 anterior spinal roots running through spinal dura mater was higher than that of S 2 ~ 4 anterior spinal roots originating from spinal cord ;

在椎间孔矢状面上脊神经前根位于背根神经节的腹侧5或7点钟处。

On the sagittal aspect of the foramina , the ventral root were located in 5:00 or 7:00 of the dorsal root ganglion .

目的：选择性切断脊神经前根和后根，建立单纯运动神经和感觉神经损伤的动物模型。

Objective : To initiate the rat model of simple motor nerve and sensory nerve injury by selective anterior rhizotomy or posterior rhizotomy .

目的：观察大鼠脊神经前根撕脱伤对盆底肌运动神经元的存活、一氧化氮合酶和N-甲基-D-天冬氨酸型受体表达的影响。

AIM : To investigate the survival of pelvic motoneurons and the expression of nitric oxide synthase ( NOS ) and N-methyl-D-aspartate ( NMDA ) in rats following lumbosacral ventral root avulsion .

目的：为下腹壁反射重建膀胱功能手术时脊神经前根和吻接平面的选择以及脊神经前根的定位提供解剖学依据。

Objective : To provide anatomic basis for the choice of proper spinal roots , idea level of cross anastomosis and the identification of anterior spinal roots during the operation of bladder functional reconstruction with lower abdominal reflexes .

结果：脊神经的前根和后根其一二阶导数光谱较为相近，不能直观进行鉴别；

Results : The results showed that the anterior and posterior roots had quite similar first-derivative and second-derivative spectra of the near-infrared spectroscopy and were unable to be distinguished .

结论在选择性脊神经根切断术中，齿状韧带可作为一标志，脊神经前、后根可通过齿状韧带加以鉴别和定位，特别在颈部。

Conclusions Denticulate ligament was a mark and could be used to identify and localize the spinal nerve anterior and posterior roots in the SPR or SAR , especially for the cervical nerve roots .
