Asurgeon removes two pieces of muscle from different parts of the body. muscle a has alternating dark and light markings. muscle b does not. which of these statements is most likely true? (2 points) muscle a is smooth muscle; muscle b is cardiac or skeletal muscle. muscle a is skeletal or smooth muscle; muscle b is cardiac muscle. muscle a is cardiac muscle; muscle b is skeletal or smooth muscle. muscle a is cardiac or skeletal muscle; muscle b is smooth muscle.

  1. C. skeletal muscle; cardiac muscle, smooth muscle, and organs

    Explanation:The somatic nervous system has voluntary control of body movements via skeletal muscles, whereas the autonomic nervous system is responsible for controlling involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.Skeletal muscle system (SNS) regulating voluntary skeletal muscle contraction and autonomous nervous system ( ANS) regulating involuntary control of smooth, cardiac muscles and glands.

    Hope this helps.

  2. The correct option is this: CARDIAC MUSCLE DOES NOT USE THE SLIDING FILAMENT MECHANISM FOR CONTRACTION, SKELETAL MUSCLE DOES.

    Explanation:

    The muscles found in the heart are called cardiac muscles while the ones found in the skeleton are called skeletal muscles. Both muscles have some differences and similarities. One similarity between the two is that both of them are striated muscles. Also, both cardiac and skeletal muscles use the sliding filament mechanism for contraction.

    The differences include the following:

    1. Skeletal muscles are involved in voluntary movement while cardiac muscles engage in involuntary movement.

    2. Cardiac muscles can not survive for long in the absence of oxygen while skeletal muscle can adapt to absence of oxygen.

    3. Cardiac muscles cell have more mitochondria compare to skeletal muscles cells.

  3. Muscle A is cardiac or skeletal muscle; muscle B is smooth muscle

    Explanation:

    In order to answer the question, we need to review the anatomy of muscles. Basically, muscles can be divided into 2 types.

    Striated MusclesSmooth Muscles

    Striated muscles are further divided into skeletal and cardiac muscles. Striated muscles possess contractile unit sacrcomeres which is responsible for its striated (striped) appearance under the microscope.

    Smooth muscles do not possess striations and appear smooth under the microscope.

    Coming back to the answer choices;

    Muscle A is cardiac or skeletal muscle; muscle B is smooth muscle.

    This is the correct option. It is stated in the question that Muscle A possesses light and dark markings (striations). Only striated muscle type possesses striations. Therefore, it correctly matches. It is further stated in the question that muscle B does not possess dark and light markings hence it implies that muscle B is smooth muscle and this answer choice correctly matches it.

  4. A. Cardiac and skeletal muscles are striated.

    D. Heart and digestive muscles are involuntary muscles.

    E. Smooth and skeletal muscles are involved in movement.

    F. Smooth and skeletal muscles are involved in movement.

    Explanation: I took the test, got them right! Also it says it directly in the lessons/Assignments 🙂

  5. A: Cardiac and skeletal muscles are striated.

    D: Heart and digestive muscles are involuntary muscles.

    E: Heart and digestive muscles are involuntary muscles.

    F: Cardiac muscles work to pump blood.

  6. Cardiac and skeletal muscles are striated

    Heart and digestive muscles are involuntary muscles

    Smooth and skeletal muscles are involved in movement

    Cardiac muscles work to pump the blood

    Explanation:

  7. A. Cardiac and skeletal muscles are striated

    D. Heart and digestive muscles are involuntary muscles

    E. Smooth and skeletal muscles are involved in movement

    F. Cardiac muscles work to pump blood
