Verified Answer
Synaptic vesicles discharge _________ at the neuromuscular junction.a)...
The membrane of the discharged synaptic vesicles is subsequently retrieved from the presynaptic plasma membrane by endocytosis. An axon terminal at a neuromuscular junction typically releases a few hundred of its many thousands of synaptic vesicles in a response to a single action potential.

Neurotransmitter at Neuromuscular Junction
Neuromuscular junction is the synapse between a motor neuron and a muscle fiber. At the neuromuscular junction, the motor neuron releases a neurotransmitter, which binds to the receptors on the muscle fiber's membrane, causing the muscle to contract.
The neurotransmitter that is discharged at the neuromuscular junction is acetylcholine.
Acetylcholine
Acetylcholine is a neurotransmitter that is involved in many functions, including muscle contraction, learning, and memory. It is synthesized in the presynaptic neuron and stored in vesicles. When an action potential arrives at the presynaptic neuron, it causes the release of acetylcholine from the vesicles into the synaptic cleft.
In the case of the neuromuscular junction, the acetylcholine released by the motor neuron binds to the receptors on the muscle fiber's membrane, causing the muscle to contract. The acetylcholine is then broken down by an enzyme called acetylcholinesterase, which is present in the synaptic cleft.
Conclusion
In conclusion, the neurotransmitter that is discharged at the neuromuscular junction is acetylcholine. Acetylcholine is synthesized in the presynaptic neuron and stored in vesicles. When an action potential arrives at the presynaptic neuron, it causes the release of acetylcholine from the vesicles into the synaptic cleft. The acetylcholine then binds to the receptors on the muscle fiber's membrane, causing the muscle to contract.
