Partial denervation of the sternocostalis muscle was achieved by sectioning two out of the five of its intercostal nerves. The terminal sprouting response was markedly increased compared to that found following section of only one nerve. The increase in the response was greater for B type than for C type end plates, although B type end plates appear unable to produce terminal sprouts longer than 20 micron after partial denervation. Double nerve section allowed terminal sprouts from C type end plates to increase the length up to three days, after which time they appeared to retract. It is postulated that the onset of collateral sprouting resulted in reinnervation of empty end plate sites and hence removed the target for terminal sprouts.
通过切断胸肋肌五条肋间神经中的两条来实现该肌肉的部分去神经支配。与仅切断一条神经后相比，终末芽生反应显著增强。B型终板的反应增加幅度大于C型终板，尽管部分去神经支配后B型终板似乎无法产生长度超过20微米的终末芽。切断两条神经使C型终板的终末芽长度增加，持续三天，此后它们似乎回缩。据推测，侧支芽生的开始导致空终板部位重新获得神经支配，从而消除了终末芽的靶点。
