脊椎动物的神经肌肉接头已经被很好地研究，很久以来人们认为乙酰胆碱是在这里被使用的唯一神经递质。

The vertebrate neuromuscular junction has been very well studied, and it has long been thought that acetylcholine was the only neurotransmitter used there.

持续长时间牵拉造成神经肌肉接头处的损害亦导致肌肉去神经支配。

Damage to the neuromuscular junction following prolonged retraction can also lead to muscle denervation.

第一，川楝素以先易化后抑制的双相作用干扰神经递质释放，阻遏神经肌肉接头和中枢神经突触的突触传递。

The first is that by interfering with neurotransmitter release by causing an initial facilitation, TSN eventually blocks synaptic transmission at both the neuromuscular junction and central synapses.
