2分钟神经科学:神经肌肉接点

在这个视频中,我将讨论神经肌肉接头.这个词神经肌肉接头是指一个突触之间的运动神经元和肌肉纤维;这里的活动是肌肉收缩和运动的必要条件。在神经肌肉连接处突触剑头运动神经元的一部分位于肌肉的一个特殊区域上,叫做终板。突触钮扣释放acetycholine,它穿过突触间隙并激活肌肉纤维上的乙酰胆碱受体。这导致肌肉细胞兴奋,导致肌肉收缩。过量的乙酰胆碱被该酶从突触间隙中除去乙酰胆碱酯酶

In this video I discuss the neuromuscular junction. The term neuromuscular junction refers to a synapse between a motor neuron and muscle fiber; activity here is essential for muscle contraction and thus movement. At the neuromuscular junction, the synaptic boutons of a motor neuron are situated over a specialized region of muscle called the end plate.
