AP PSYCHOLOGY

Detailed explanation-1: -When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).

Detailed explanation-2: -The presence of the pore allows for the release of neurotransmitter into the synaptic cleft. The process occurring at the axon terminal is exocytosis, which a cell uses to exude secretory vesicles out of the cell membrane.

Detailed explanation-3: -“Neurons communicate with each other through electrical and chemical signals, ” explains Barak. “The electrical signal, or action potential, runs from the cell body area to the axon terminals, through a thin fiber called axon. Some of these axons can be very long and most of them are very short.

Detailed explanation-4: -The axon terminal is the part of the axon that releases the neurotransmitters that relay signals across a synapse.

Detailed explanation-5: -If the signal reaches the terminal buttons, they are signalled to emit chemicals known as neurotransmitters, which communicate with other neurons across the spaces between the cells, known as synapses.
