Cats received unilateral or bilateral horseradish peroxidase (HRP) injections into various portions of the diaphragm. In two experiments one of the cut cervical roots of the phrenic nerve was immersed in HRP. The phrenic motoneurons located in the fifth and occasionally the fourth cervical segment send their axons, via the upper phrenic root, to pars sternalis and pars costalis of the diaphragmatic dome whereas the neurons of the sixth segment innervate preferentially the dorsal portion both crura and dome. No evidence of contralateral innervation of the diaphragm was obtained.
猫接受了将辣根过氧化物酶（HRP）单侧或双侧注射到膈肌不同部位的操作。在两个实验中，膈神经的一根切断的颈根被浸入HRP中。位于第五颈段且偶尔位于第四颈段的膈运动神经元通过膈上根将其轴突发送至膈穹窿的胸骨部和肋部，而第六颈段的神经元则优先支配两个膈脚和膈穹窿的背侧部分。未获得膈肌对侧神经支配的证据。
