General Information
Term synaptic vesicle ID (Ontology) GO:0008021 (Gene Ontology)
Definition A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.[ PubMed:10099709 PubMed:12563290 ]
