"NettetNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal. " - Movement of electrical impulses in the cell

A synapse is where the axon tip stops. A synapse is the point where each axon tip connects to the following structure.

NettetElectrical potentials are generated across the membranes of neurons—and, indeed, all cells—because (1) there are differences in the concentrations of specific ions across nerve cell membranes, and (2) the membranes are selectively permeable to some of these ions.
