AP PSYCHOLOGY

Detailed explanation-1: -Neurotransmitters are located in a part of the neuron called the axon terminal. They’re stored within thin-walled sacs called synaptic vesicles. Each vesicle can contain thousands of neurotransmitter molecules.

Detailed explanation-2: -Neurotransmitters are synthesized in the cell body and are transported to the terminal synaptic buttons of the axon where they are encapsulated into vesicles and stay close to the synaptic region of the button.

Detailed explanation-3: -An action potential travels the length of the axon and causes release of neurotransmitter into the synapse. The action potential and consequent transmitter release allow the neuron to communicate with other neurons. Neurotransmitter – A chemical released from a neuron following an action potential.

Detailed explanation-4: -There the calcium ions interact with the neurotransmitter containing vesicles (membrane-bound containers) causing them to fuse with the cell membrane, and release the neurotransmitters into the synaptic cleft.

Detailed explanation-5: -Inside the axon terminal of a sending cell are many synaptic vesicles. These are membrane-bound spheres filled with neurotransmitter molecules. There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.
