Answer:
A synapse transmits an eletric impulse by means of flow of ions from presynaptic cell to postsynaptic cell at a gap junction.
Step-by-step explanation:
1.Synaptic impulsion means one neuron sends message to other neuron of another cell.
2.Neurons communication with one another at a junction point is called synapses.
3.Mostly synapses are chemical based communicate with target neuron by means of chemical messenger.
4.An electric synapses the plasma membrane of presynaptic and postsynaptic cells are interlinked by a gap junction.
5. Flow of ions via these channels allows send impulses directly from cell to cell.
