AP PSYCHOLOGY

Detailed explanation-1: -When the electrical impulse from the action potential reaches the end of the axon, it signals the terminal buttons to release neurotransmitters into the synapse. A neurotransmitter is a chemical that relays signals across the synapses between neurons.

Detailed explanation-2: -Neurotransmitter – A chemical released from a neuron following an action potential. The neurotransmitter travels across the synapse to excite or inhibit the target neuron.

Detailed explanation-3: -When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called neurotransmitters are released. These chemicals diffuse across the synapse (the gap between the two neurons). The chemicals bind with receptor molecules on the membrane of the second neuron.
