GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The axon terminal of a presynaptic cell, into the synaptic cleft, releases chemicals called neurotransmitters. Neurotransmitters are contained in synaptic vesicles inside the axon terminal.

Detailed explanation-3: -Neurotransmitter Release. At rest, neurotransmitter-containing vesicles are stored at the terminal of the neuron in one of two places. A small number of vesicles are positioned along the pre-synaptic membrane in places called “active zones.” This is where neurotransmitter release occurs.

Detailed explanation-4: -Synaptic vesicles are found at high density in presynaptic nerve endings, where they store neurotransmitters that they release when action potentials depolarize cells, opening voltage-dependent Ca2+ channels to increase intracellular Ca2+ concentrations.
