Skeletal and Muscular Systems

Skeletal System Match the term with the definition. Remember to shrink your screen if all the terms do not fit on the page. If you shrink after you begin matching, nothing is wrong, it just looks strange.

True False Some joints, like your neck, pivot. True False Cardiac muscles are located only in your intestines. True False The skeletal system consists of bones and the tissues connecting them. True False Smooth muscles _ are found in internal organs. are always connected to bones. are found only in the heart. are voluntary muscles. When you eat a healthful eating plan, your bones and muscles get the proper _ nutrients. oxygen. body composition. relaxation. Which statement is true? involuntary muscles connect to and move your body voluntary muscles move without you having to think about them involuntary muscles move without you having to think about them voluntary muscles connect to and control your heart The tissue inside your bones _. produce white blood cells store calcium and phosphorous produce red blood cells all of the above What makes muscles grow? Watch the video and answer the following questions. Skeletal muscle tissue can make up as much as _ percent of a person's body weight? 10% 50% 90% 20% The amount of tension a muscle can produce is the result of the: Muscle size (i.e. cross-sectional area) along with the type and number of motor units activated Neurological signal (intensity and frequency) from brain to muscle Strength and point of tendon insertion and joint angle all of the above The most commonly accepted theory of muscle growth states that _ within a muscle activate a(n) _ process that causes dormant stem cells to build and regenerate muscle tissue Microscopic tears; Inflammatory Contractions; Inhibitory Stress; Cytokines Tension; Neurological Which of the following are NOT an important factor contributing to muscle growth: Nutrition, especially protein intake Recovery, especially rest and sleep Hormones, especially thyroid Progressive mechanical overboard, especially eccentric contractions Everyday activities do not produce significant muscle growth because: Muscle growth requires going to the gym and lifting weights The body adapts to repeated demands so that movements performed regularly often do not produce enough stress to cause hypertrophy Cytokines are released during everyday activities that inhibit muscle regeneration The nervous system cannot respond by recruiting more muscle fibers to generate hypertrophy
