What does it mean?
The neuromuscular junction (NMJ) is the connection between the end of a nerve and a muscle (skeletal/cardiac/smooth) fiber. The NMJ is where electric signals, called action potentials, generated by motor neurons in the nerve interact with the muscle, causing the muscle to contract.
How do I use it in a sentence?
Movement occurs because of muscle contraction due to the release of the neurotransmitter acetylcholine at the neuromuscular junction.
