Detailed explanation-1: -Synaptic vesicles (SVs) are small, electron-lucent vesicles that are clustered at presynaptic terminals. They store neurotransmitters and release them by calcium-triggered exocytosis. SVs are made locally at the terminals and are regenerated after exocytosis.
Detailed explanation-2: -Neurotransmitters are stored in synaptic vesicles. These vesicles are located in the axon terminal of a presynaptic neuron of the central or peripheral nervous system. There are many types of neurotransmitters and they may be either excitatory or inhibitory.
Detailed explanation-3: -An axon terminal. 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-4: -Neurotransmitters are stored in synaptic vesicles and are released by fusion of these vesicles to the plasma membrane.
