The gap between two neurons across which a nerve impulse is transmitted (chemically) is the:

1. SYNAPSE is the junction between two neurons (or between a neuron and a muscle). 2. Electrical impulse triggers release of NEUROTRANSMITTER chemicals from the axon terminal. 3. They diffuse across the synapse to bind receptors on the next dendrite → new electrical signal. _Source: syllabus Science Ch 6 §6.1.1 The Neuron_
