Abstract

The pattern of polyneuronal innervation in the sculpinMyoxocephalus scorpius was examined. The majority of fast fibres in sculpin are innervated by both adjacent nerves, and <15% receive input from sub-adjacent myotomes. Stimulation through both adjacent and sub-adjacent nerves results in muscle action potentials. Each adjacent nerve supplies 2-5 axons to a given fibre. A typical fibre is probably innervated by around 4-6 axons, and pre-terminal branching accounts for the 8-20 endplates present on these fibres.

摘要

研究了鮟鱇鱼Myoxocephalus scorpius 的多神经元神经支配模式。鮟鱇鱼的大多数快肌纤维均由相邻的两条神经支配，而只有<15%的纤维接受来自次相邻肌节的输入。通过相邻和次相邻神经的刺激会产生肌肉动作电位。每条相邻的神经向给定的纤维提供 2-5 个轴突。典型的纤维可能由大约 4-6 个轴突支配，而末梢分支解释了这些纤维上存在的 8-20 个终板。
