How is an impulse transmitted across electrical synapses?

A synapse is a junction between two neurons that allows the transmission of a nerve impulse from one neuron to another.rAt electrical synapses, the membranes of pre- and post-synaptic neurons are in close proximity, allowing electrical current to flow directly from one neuron into the other across these synapses. Transmission of an impulse across electrical synapses is similar to impulse conduction along a single axon.The membranes of pre- and post-synaptic neurons at a chemical synapse are separated by a fluid-filled space called the synaptic cleft.The membranes of pre- and post-synaptic neurons at a chemical synapse are separated by a fluid-filled space called the synaptic cleft.When an impulse arrives at the axon terminal, it stimulates the movement of the synaptic vesicles towards the membrane where they fuse with the plasma membrane and release their neurotransmitters in the synaptic cleft.
