Definition English:
|
|
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. |

between nerves; differentiate entry term NEURAL TRANSMISSION from NEURAL CONDUCTION (along a single nerve); consider also NEURAL INHIBITION; neuromusc transm = NEUROMUSCULAR JUNCTION /physiol + SYNAPTIC TRANSMISSION
