[解剖] presynaptic membrane
- 突触前轴突终末端动作电位到达时,突触小泡和突触前膜紧密相连。
Synaptic vesicles fuse with the presynaptic membrane upon the arrival of an action potential at the presynaptic axon terminal. - 突触后膜上化学门控离子通道的开放比例与突触前膜电位呈正相关;
And the opening proportion of chemical-gated ion channels on postsynaptic membrane was positively related to the potential of presynaptic membrane. - 结论君复康治疗海洛因成瘾者稽延性戒断症状有效,其作用靶点是多巴胺(DA)能神经元突触前膜的DAT。
Conclusion U'finer was effect to treat patients with heroin prolonged withdrawal symptom, its effect target was DAT in presynaptic membrane of DA neurons.
