Answer:
The neuromuscular junction is a connection between a neuron and a muscle fiber.
Step-by-step explanation:
The neuromuscular junction is formed by the connection between the axon terminal of a neuron and a muscle fiber. This union forms a bridge between the terminal button of a neuron and the muscle fiber membrane, through it the terminals of the neuron are connected with the motor terminal plates, just where the nerve impulses are received. This allows the contraction of muscle fiber, with acetylcholine being the neurotransmitter of muscle stimulation.
