synapse[sin′aps′, si naps′]
- The definition of a synapse is the junction between two neurons or nerve cells where there is a small gap that neurotransmitters help nerve impulses to cross.
When a neuron releases a neurotransmitter which then binds to receptors located within the plasma membrane of a cell, initiating an electrical response or exciting or inhibiting the neuron, this is an example of a chemical synapse.
