Acetylcholine is the fundamental neurotransmitter that transmits information from nerve cells to muscles. It is released by synaptic vesicles and binds to receptors on the muscle membrane.
In order to stimulate muscle contraction, acetylcholine is released from the SYNAPTIC VESICLES into the synaptic cleft.
Synaptic vesicles are a type of small organelle clustered at presynaptic terminals.
These vesicles (synaptic vesicles) are responsible for the uptake, storage, and release of different neurotransmitters.
