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