单词	presynaptic
释义	presynaptic /ˌpriːsɪˈnaptɪk / adjective Physiology Relating to or denoting a nerve cell that releases a transmitter substance into a synapse during transmission of an impulse: the presynaptic terminal... Instead, transmission is accomplished by the release of a chemical neurotransmitter substance from the presynaptic fibre. The toxin irreversibly binds to presynaptic cholinergic receptors at motor nerve terminals and is subsequently internalized. The authors proposed a mechanism of action whereby the calcium channel blocker inhibited the presynaptic release of neurotransmitters. Derivatives presynaptically adverb ... Cocaine blocks the reuptake of catecholamines presynaptically. Glutamate is released presynaptically and binds to a postsynaptic receptor gating a cation-selective channel, thus depolarizing the post-synaptic cell. We find that the occurrence of glia postsynaptically is strikingly higher than presynaptically, in both types of synapses.
