What Are Synaptic Vesicles?
Synaptic vesicles are structures found in the human body responsible for storing neurotransmitters. Neurotransmitters are basically chemicals designed to carry signals from neurons to other cells in the body. This is done through synapses, or junctions, which provides the passageway for the signals. These synaptic vesicles are also known as neurotransmitter vesicles. A vesicle is often described as a bubble made of liquid sitting inside of a different liquid. To be more precise, it is a small sac surrounded by a membrane whose function is to store or carry other substances. In the case of synaptic vesicles, these substances are the chemicals known as neurotransmitters. The thin membrane of synaptic vesicles is called a lipid bilayer. This membrane is comprised of two separate lipid molecules. Nearly every living organism contains cell membranes which are made of this lipid bilayer. This membrane is responsible for ensuring that molecules such as proteins and ions remain in their proper
