  1. Question 1

    Q1. A patient with a neurological disorder experiences muscle weakness. Which type of muscle fiber is primarily affected?

    • A) Type I slow-twitch fibers
    • B) Type II fast-twitch fibers
    • C) Type III intermediate fibers
    • D) Type IV fatigue-resistant fibers

    Answer: Type II fast-twitch fibers

    Explanation: Type II fast-twitch fibers are primarily affected in muscle weakness, as they are responsible for rapid muscle contraction and are more susceptible to fatigue.
