1.But by blocking neurotransmitters released by interneurons, tetanus toxin causes uncontrollable muscle contractions and spasms.

但破伤风毒素通过阻断中间神经元释放的神经递质，会导致不受控的肌肉收缩痉挛。

2.Nerve endings soak up this toxin, drawing it into the brain and spinal cord where it wreaks havoc on interneurons.

神经末梢渗这种毒素，并将其带脑和脊髓，对中间神经元造成严重破坏。

3.And basically, the interneurons do the thinking.

基本上，中间神经元负责思考。机翻

4.And there are interneurons which connect the two.

并且有连接两者的中间神经元。机翻

5.Interneurons connect neurons within specific regions of the CNS.

而中间神经元连接CNS中特定区域的神经元。

6.The resulting nerve impulses zip along afferent fibers to the sacral region of the spinal cord, along interneurons, and toward the brain, eventually exciting the parasympathetic neurons and inhibiting the sympathetic system.

由此产生的神经脉冲沿着传纤维快速到达脊髓的骶骨区域，沿着中间神经元，并朝向脑，最终刺激副交感神经细胞并抑制交感神经系统。
