    Where do motor neurons and muscle fibers meet?

    • Sarcoplasm

    • Synapse

    • Myofibrils

    • Neuromuscular junction

    Correct Answer
    A. Neuromuscular junction
    Explanation
    Motor neurons and muscle fibers meet at the neuromuscular junction. This is the site where the motor neuron's axon terminal and the muscle fiber's membrane come into close proximity. At the neuromuscular junction, the motor neuron releases neurotransmitters, specifically acetylcholine, which binds to receptors on the muscle fiber's membrane. This binding triggers a series of events that ultimately lead to muscle contraction. Therefore, the neuromuscular junction is the critical point of communication between the nervous system and the muscular system.
