Question

What does a neural signal reaching the neuromuscular junction release?

Answer 1

Neuromuscular junction (NMJ):

1. Neuromuscular junction is a highly specialised synapse that connects a motor neuron's nerve terminal to its muscle fiber.
2. Neuromuscular junction is the site for the transmission of action potential from nerve to the muscle.
3. Neuromuscular junction is also a site for many diseases and pharmacological drugs.
4. When a neutral signal reaches the NMJ, it causes a neurotransmitter (acetylcholine) to be released, resulting in an action potential in the sarcolemma.
