synapse 突触 A junction between the axon of one neuron (presynaptic) and the dendrite of another (postsynaptic). The arrival of an action potential on the presynaptic axon, provokes the secretion of neurotransmitter at the synapse, which in turn opens up ionic flow channels on the postsynaptic side of the synapse. 一种神经元(突触前)的轴突与另一个(突触后)的树突间的一类连接。到达突触前轴突的 一个冲动,引起突触处神经递质的分泌,依次在突触的突触后一侧开启离子流通道。 |
