Verified step by step guidance1
Understand the basic structure of a neuron, which includes the cell body, dendrites, axon, and axon terminals.
Recognize that the axon terminals are the part of the neuron responsible for transmitting impulses to neighboring neurons.
Learn that axon terminals contain synaptic vesicles, which are small sacs that store neurotransmitters.
When an impulse reaches the axon terminal, it triggers the release of neurotransmitters from the synaptic vesicles into the synaptic cleft, the space between neurons.
These neurotransmitters then bind to receptors on the neighboring neuron, allowing the impulse to be transmitted chemically across the synapse.
