Detailed explanation-1: -Neurotransmitters are packaged into synaptic vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse. The axonal terminals are specialized to release the neurotransmitters of the presynaptic cell.

Detailed explanation-2: -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-3: -The terminal part of the axon and collaterals tapers progressively. These parts are called telodendron and continue with the synapse (synaptic knob or button) which represents the specialized structure that comes into contact with another neuron (soma, axon or dendrite), or muscle fiber.

Detailed explanation-4: -The neurotransmitters are stored in synaptic vesicles located at the axon terminals, which are released when the synaptic vesicles fuse with the neural membrane following an influx of Ca2+ ions. The neurotransmitters then bind with receptors on the postsynaptic cell to carry out the communication.

Detailed explanation-5: -The part of the neuron that can release neurotransmitters is the axon terminal. From the axon terminals, neurotransmitters will be released and travel across the synapse to bind to receptors on other neurons, glands, or muscle cells.
