Answer:
A neuromuscular junction is a junction between a <em>nerve fiber</em> and a <em>muscle cell.</em>
Explanation:
<em>A neuromuscular junction (or myoneural junction) is a site of chemical communication between a nerve fiber and a muscle cell, is analogous to the synapse between two neurons. </em>
A motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles binding to the receptors, the channels open, and sodium ions flow into the endplate, this initiates the end-plate potential, the electrical event that leads to contraction of the muscle fiber.
