Weba synapse- is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell synaptic gap-The minute space between the cell membrane of an axon terminal and of the target cell with which it synapses. synaptic cleft. Web5 Steps to Chemical Synaptic Transmission In a gist: The electrical signal cannot “jump” over that gap. Instead, at the point of synaptic junction between two neurons, the presynaptic neuron (at the presynaptic terminal) “translates” the electrical signal into a chemical message (the neurotransmitter) – Step 1 & 2.
