Muscular System Quizzes & Trivia

  • 2. 

    The study of the muscular system is known as

    • Kinesiology

    • Pathophysiology

    • Myology

    • Biology

    • Neurology

    Correct Answer
    A. Myology
    Explanation
    Myology is the study of the muscular system, including the structure, function, and diseases of muscles. It involves understanding how muscles are formed, how they contract and relax, and how they interact with other systems in the body. Kinesiology is the study of human movement, pathophysiology is the study of abnormal physiological processes, biology is the study of living organisms, and neurology is the study of the nervous system. However, myology specifically focuses on the muscular system, making it the correct answer.

    All of the following are functions of muscles except

    • Stability

    • Heat production

    • Control of openings

    • Secretion

    • Respiration

    Correct Answer
    A. Secretion
    Explanation
    Muscles are primarily responsible for movement and stability in the body. They generate heat during contraction, control the openings of various body structures, and facilitate respiration. However, muscles do not have the ability to secrete substances. Secretion is typically carried out by specialized glands in the body, such as the salivary glands, sweat glands, or endocrine glands. Therefore, secretion is not a function of muscles.

    What term best describes the relationship between the pronator quadratus and supinator?

    • Fixators

    • Antangonist

    • Synergists

    • Prime movers

    • Depressors

    Correct Answer
    A. Antangonist
    Explanation
    The pronator quadratus and supinator are muscles that have opposite actions. The pronator quadratus pronates the forearm (rotates it inward), while the supinator supinates the forearm (rotates it outward). Therefore, they work against each other, making them antagonists.

  • 5. 

    Which of the following describes an appearance of red muscular tissue emerging directly from bone rather than being separated from it by an obvious tendon?

    • Fleshy attachment

    • Indirect attachment

    • Inversted attachement

    • Insertion

    • Origin

    Correct Answer
    A. Fleshy attachment
    Explanation
    A fleshy attachment refers to the connection of red muscular tissue directly to the bone, without the presence of a distinct tendon separating them. This means that the muscle appears to emerge directly from the bone, giving it a fleshy appearance.

    What separates groups of mucles

    • Epimysium

    • Fasciles

    • Perimysium

    • Fascia

    • Endomysium

    Correct Answer
    A. Fascia
    Explanation
    Fascia is the correct answer because it is a connective tissue that separates and surrounds groups of muscles. It provides support and protection to the muscles, allowing them to move independently and smoothly. Fascia also helps in distributing force and tension throughout the body, aiding in efficient movement and preventing injury.

    Which term below best describes the deltoid

    • Fusiform

    • Intrinsic

    • Involuntary

    • Extrinsic

    • Parallel

    Correct Answer
    A. Extrinsic
    Explanation
    The term "extrinsic" best describes the deltoid because it refers to a muscle that is located outside of or separate from the structure it is associated with. In the case of the deltoid, it is an extrinsic muscle of the shoulder, meaning it is located outside of the shoulder joint.

    The rectus femois is what muscle shape

    • Fusiform

    • Parallel

    • Triangular

    • Elongated

    • Pennate

    Correct Answer
    A. Pennate
    Explanation
    The rectus femoris is a pennate muscle. Pennate muscles have fibers that are arranged obliquely to the tendon, resembling the shape of a feather. This arrangement allows for a greater number of muscle fibers to be packed into a smaller space, resulting in a stronger contraction. The pennate shape also provides increased stability and control during movement. Therefore, the rectus femoris, being a pennate muscle, has a structure that allows for efficient force generation and control.
