    Skeletal Muscle Physiology: Exercise

    Uploaded by

    Ron Richard Callera
    This document contains a review sheet with questions about skeletal muscle physiology. It asks the student to define key terms related to muscle contraction like motor unit, twitch, threshold and fatigue. It also asks the student to describe processes like excitation-contraction coupling, the roles of acetylcholine, the phases of a muscle twitch, the differences between isometric and isotonic contractions, and factors like stimulus intensity and frequency. The goal is for the student to demonstrate their understanding of fundamental concepts in muscle physiology.

    8. What is the key variable in an isometric contraction?

    9. Define the term maximal stimulus.

    10. What has happened in the muscle when the maximal stimulus is achieved?

    11. What is the difference between stimulus intensity and stimulus frequency?

    12. Circle the correct boldfaced term.
