In chick embryo leg muscles, elimination of polyneuronal innervation takes place one to 1.5 days earlier in the thigh muscle m. ambiens than in the foot muscle m. flexor hallucis brevis. Initial formation of synapses takes place 2-3 days earlier in the proximal than the distal muscle, so the length of time synapses have been active may be a factor in the control of elimination of polyneuronal innervation during development.
在鸡胚腿部肌肉中,多神经元支配的消除在股部的栖肌中比足部的拇短屈肌早1至1.5天发生。突触的初始形成在近端肌肉中比远端肌肉早2 - 3天发生,因此突触活跃的时间长度可能是发育过程中多神经元支配消除控制的一个因素。
