sensory root

【 Conclusion 】 MRCT and SRCT can be used as the new electrodiagnostic parameters for estimation of the sensory nerve root function in patients with S1 radiculopathy.

【结论】MRCT和SRCT可作为评价神经根功能的指标，为骶1神经根病的无创性电诊断提供了一个新的方法。

Each spinal nerve is attached to the spinal cord a sensory and a motor root.

都以感觉纤维(背侧根)和运动纤维(腹侧根)连接于脊髓上.

Conclusions: Gradually, section of sensory root of trigeminal nerve was inclined not to be applied.

结论：三叉神经感觉根切断术逐渐少用。

Dorsal root ganglion ( DRG) neurons are primary sensory neurons.

背根神经节（DRG）是躯体和内脏传入的基础神经元，作为基本的感觉传入系统，把外周的信息传递给中枢神经系统，它在全身的运动协调方面起着重要的作用。

Methods: Two trigeminal nerve root and the trigeminal nerve sensory root ( TNSR) were obtained from 10 anatomic cadav ers and were paraffin embedded.

方法：从尸体（10具）上取三叉神经根标本，对三叉神经感觉根（TNSR）进行石蜡包埋及连续切片，并系统观察；

Seven patients presented with paraparesis. Five patients had sensory disturbances. Three patients suffered both limb weakness and sensory dysfunction. Five patients showed the corresponding nerve root pain.

7例患者有运动障碍，5例患者有感觉障碍，3例患者既有肢体乏力又有感觉障碍，5例患者表现为相应部位的神经根痛，1例有小便失禁。

Retrograde tracing showed plenty of positive sensory neurons in L3~ 6 dorsal root ganglion and motor neurons in the anterior corn of spinal cord labelled by true blue, the resulted verified the afferent pathway of regenerative sensory and motor nerve fibres was unobstructed.

逆行示踪检测显示大量真蓝标记阳性的L3～6背根神经节感觉神经元和脊髓前角运动神经元，证实再生感觉神经纤维和运动神经纤维传入通路均通畅。
