Detailed explanation-1: -In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the 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.
Detailed explanation-3: -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-4: -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.
