A synapse is a structure that allowssignal transmissionbetween a neuron and a target cell. The signal flows according to theaction potential, so the electric impulse is received at the dendrites of thepresynaptic neuron胞体、集成,和输出信号al is given to thepostsynaptic cellat its axon terminals at a synapse.

Depending on the type of signal, there are two main types of synapses:
The majority of synapses are chemical, so communication is performed using neurotransmitters. In the electrical synapses, ions flow between cells in a direct manner.
