Definitions related to synaptic transmission:
-
(neural transmission) Communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse.CRISP ThesaurusNational Institutes of Health, 2006
-
(neuronal transmission) Any process in which a presynaptic cell transfers a signal to a postsynaptic cell, by either release of a neurotransmitter or by passage of an electrical current via specialized channels. This process is essential to all neuronal functions.NCI ThesaurusU.S. National Cancer Institute, 2021
-
The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(transmission of nerve impulse) The neurological system process in which a signal is transmitted through the nervous system by a combination of action potential propagation and synaptic transmission.Gene Ontology DictionaryGene Ontology Consortium, 2021
-
A neuron generates and propagates an action potential along its axon, then transmits this signal across a synapse by releasing neurotransmitters, which trigger a reaction in another neuron or an effector cell (eg, muscle cells, most exocrine and endocrine cells). Neurotransmitters that are released bind to receptors on another neuron....Merck & Co., Inc., 2020
