家兔膈肌放电家兔呼吸运动的调节家兔呼吸运动调节膈肌放电兔膈肌放电试验家兔呼吸运动兔膈肌放电实验呼吸运动的调节呼吸运动呼吸运动是指文档格当膈肌收缩时，穹窿顶变平，下移和稍向前运动，中心腱也下降，因为使胸廓的上下径增大，胸腔内压力低于大气压，产生吸气。无论是在整体或离体情况下，也无论是直接刺激或间接刺激，总是先引起兴奋，然后由兴奋触发收缩机制，引起肌肉收缩。利用针形电极插入膈肌，所记录到的肌肉电活动称为膈肌放电。

家兔膈肌放电与呼吸运动实验关树文实验目的n学习掌握计算机生物信号系统的使用n掌握记录呼吸及膈肌放电的方法，同时加深对呼吸运动调节的认识。n掌握气管插管术等手术操作实验原理n膈肌为吸气肌。当膈肌收缩时，穹窿顶变平，下移和稍向前运动，中心腱也下降， 因为使胸廓的上下径增大，胸腔内压力低于大气压，产生吸气。n无论是在整体或离体情况下，也无论是直接刺激或间接刺激，总是先引起兴奋，然后由兴奋触发脑干呼吸中枢的节律性冲动发放，通过脊髓的膈神经及肋间神经下行传导到膈肌与肋间肌，从而产生节律性的呼吸运动。因此，引导膈神经传出纤维的放电和膈肌的放电，可直接反映脑干呼吸中枢的活动。电极插入膈肌，所记录到的肌肉电活动称为膈肌放电。无论是直接刺激或间接刺激，总是先引起兴奋，然后由兴奋触发收缩机制，引起肌肉收缩。
