Questions and Answers
  • 1. 

    The Costal cartilage serves to prolong the ribs forward and contributes to the elasticity of the walls of the thorax.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The costal cartilage is a flexible connective tissue that connects the ribs to the sternum, allowing for movement and flexibility in the thoracic cage. It serves to prolong the ribs forward, extending their reach and providing support to the chest wall. Additionally, the costal cartilage contributes to the elasticity of the thoracic wall, allowing for expansion and contraction during breathing. Therefore, the statement that the costal cartilage serves to prolong the ribs forward and contributes to the elasticity of the thorax is true.

    The inferior portion of the thorax is made up of

    • A.

      Costal cartilage

    • B.

      Sternum

    • C.

      Thoracic inlet

    • D.

      Diaphragm

    Correct Answer
    D. Diaphragm
    Explanation
    The diaphragm is the correct answer because it is the main muscle responsible for breathing and separates the thoracic cavity from the abdominal cavity. It is a dome-shaped muscle that contracts and relaxes to create changes in thoracic pressure, allowing for inhalation and exhalation. The other options, such as costal cartilage, sternum, and thoracic inlet, are not directly involved in the inferior portion of the thorax or the process of breathing.

    • C.

      Thoracic inlet

    • D.

      Cervical rib

    Correct Answer
    C. Thoracic inlet
    Explanation
    The thoracic inlet refers to a hole surrounded by a bony ring located between the T1 vertebrae posteriorly and the manubrium anteriorly. This anatomical structure serves as a passageway for several vital structures, such as the trachea. The first pair of ribs and cervical rib are not directly associated with the thoracic inlet.

    The chief muscle of inspiration, separates abdominal cavity from thoracic cavity and moves inferiorly on deep inspiration and superiorly on expiration.

    Correct Answer
    Diaphragm
    Explanation
    The diaphragm is the chief muscle of inspiration that separates the abdominal cavity from the thoracic cavity. During deep inspiration, the diaphragm moves inferiorly, allowing the lungs to expand and fill with air. On expiration, the diaphragm moves superiorly, pushing air out of the lungs. This muscle plays a crucial role in the process of breathing and is essential for proper lung function.

    In regards to the Thoracic Contents; the respiratory system is composed of the lungs, trachea and the _____________

    Correct Answer
    Bronchi
    Explanation
    The respiratory system is composed of the lungs, trachea, and bronchi. The bronchi are the main air passages that branch off from the trachea and lead into the lungs. They further divide into smaller tubes known as bronchioles, which eventually end in tiny air sacs called alveoli. The bronchi play a crucial role in facilitating the flow of air into and out of the lungs, allowing for the exchange of oxygen and carbon dioxide.
