In tetanus, Renshaw cells fail to work and the alpha motor neuron keeps firing without any inhibitory control, causing muscle rigidity and spasm.

破伤风患者中，闰绍细胞失去其功能，α运动神经元失去上级抑制，持续兴奋引起肌肉强直收缩和痉挛。

The role of Renshaw cells and inhibitory neurotransmitters is to fine-tune the action of the alpha motor neuron, which is in charge of sending the actual signal for contraction to the muscle.

闰绍细胞和抑制性神经递质可调整α神经元的运动；α神经元负责向肌肉发送收缩信号。

All right as a quick recap, Clostridium tetani is a sporulating, gram-positive, bacillus anaerobe that makes the toxin tetanospasmin, which causes tetanus by disrupting the release of inhibitory neurotransmitters from Renshaw cells.

得！快速复习一下：破伤风梭菌是一种产芽孢的革兰氏阳性厌氧棒状杆菌，能够产生引起破伤风的罪魁祸首破伤风痉挛毒素；该毒素通过干扰闰绍细胞中抑制性神经递质的释放而致病。
