Some Aspects of the Release of the Adrenergic Transmitter,rious previous explanations for this phenomenon appear at present to be unlikely. The current view is that the results are better explained as due to an increase in the amount of transmitter released per nerve impulse from the nerve endings. This indicates that the amount of transmitter released per作者: PET-scan 時(shí)間: 2025-3-22 12:15 作者: refraction 時(shí)間: 2025-3-22 12:54
