Synaptic Vesicles and Exocytosis
Annual Review of Neuroscience, 1994Neurons transmit information by releasing neurotransmitters from presynaptic nerve endings, In the resting stage , transmitters are stored in small organelles of uniform size and shape , the synaptic vesicles . When an action potential arrives in the nerve terminal , the membrane depolarizes and voltage-gated Ca2+ channels open .

Synaptic vesicle life cycle and synaptic turnover
Journal of Physiology-Paris, 1993Cholinergic synaptic vesicles contain a mixture of soluble low molecular mass constituents. Besides acetylcholine these include Ca2+, ATP, GTP, small amounts of ADP and AMP, and also the diadenosine polyphosphates Ap4A and Ap5A. In synaptic vesicles isolated from the electric ray these diadenosine polyphosphates occur in mmol concentrations and might ...

Synaptic vesicles are the characteristic organelles of the presynaptic nerve terminals of chemical synapses (i.e., those utilizing the release of a specific chemical transmitter substance to bring about synaptic transmission). They are normally 45–50 nm in diameter and must be among the most homogeneous and uniform lipoprotein membrane organelles known.

Annual Review of Neuroscience, 2004
▪ Abstract Neurotransmitter release is mediated by exocytosis of synaptic vesicles at the presynaptic active zone of nerve terminals. To support rapid and repeated rounds of release, synaptic vesicles undergo a trafficking cycle. The focal point of the vesicle cycle is Ca2+-triggered exocytosis that is followed by different routes of endocytosis and ...

Synapses locally recycle vesicles to ensure the maintenance of neuronal communication critical for normal brain function. While several modes of vesicle regeneration are thought to exist, clathrin-mediated endocytosis (CME) is the best studied mechanism of synaptic vesicle recycling.

Most nerve terminals contain various types of vesicles which differ with regard to their appearance in the electron-microscope and presumably also their molecular properties. Profiles of cholinergic nerve terminals from e.g. motor neurons or parasympathetic fibres contain in addition to the numerous electron-lucent vesicles with a diameter of about 45 ...
