Where are the Neurotransmitters that cause skeletal muscle contraction normally stored?

Acetylcholine, the neurotransmitter responsible for causing skeletal muscle contraction, is synthesized in the cytoplasm of the presynaptic neuron. However, it is stored in specialized structures known as synaptic vesicles located within the presynaptic terminal. These synaptic vesicles serve as depots, ensuring a ready supply of acetylcholine for rapid release when an action potential reaches the presynaptic terminal. This ensures efficient neuromuscular communication and allows for precise control of skeletal muscle contraction.
