Scapula, Clavicle, And Humerus Bones Anatomy (True& False) - Quiz


Questions and Answers
  • 1. 

    Pectoralis major muscle is distally attached to bicipital groove of humerus.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The pectoralis major muscle is indeed distally attached to the bicipital groove of the humerus. This attachment allows the muscle to be involved in various movements of the shoulder joint, such as adduction, flexion, and inward rotation. The bicipital groove serves as a stable anchor point for the muscle, allowing it to exert force and contribute to these movements. Therefore, the statement "Pectoralis major muscle is distally attached to bicipital groove of humerus" is true.

    Biceps brachii is inserted into radial tuberosity.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The biceps brachii muscle is indeed inserted into the radial tuberosity. This is a bony prominence located on the radius bone of the forearm. The insertion point of the biceps brachii muscle allows it to flex the forearm at the elbow joint and supinate the hand. Therefore, the statement is true.

    The spine of scapula is continued laterally as coracoid process of scapula.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the spine of the scapula is not continued laterally as the coracoid process of the scapula. The spine of the scapula is a bony ridge on the posterior side of the scapula, while the coracoid process is a separate bony projection that extends anteriorly and laterally from the scapula.

    Subscapular fossa is a large concave depression, which give origin for Subscapularis muscle.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The subscapular fossa is indeed a large concave depression located on the anterior surface of the scapula. It provides the origin for the subscapularis muscle, which is one of the four muscles that make up the rotator cuff. The subscapularis muscle plays a crucial role in internal rotation of the shoulder joint. Therefore, the statement is true.

  • 5. 

    Supraglenoid tubercle is the place of attachment of the long head of triceps brachii.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The supraglenoid tubercle is not the place of attachment of the long head of triceps brachii. The correct place of attachment for the long head of triceps brachii is the infraglenoid tubercle. Therefore, the statement is false.

  • 6. 

    Trapezoid line is a attachment point of trapezoid lig. the medial part of coracoclavicular lig. which is very stong structure.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The explanation for the correct answer being False is that the statement is not accurate. There is no such thing as a "trapezoid line" as an attachment point of the trapezoid ligament. Additionally, the coracoclavicular ligament is not a medial part of the trapezoid ligament. Therefore, the statement is incorrect and the answer is False.

  • 7. 

    Head of humerus bone faces medially, downward, and backward and separated from greater & lesser tubercles by the anatomical neck.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the head of the humerus bone actually faces laterally, not medially. Additionally, it faces upward and slightly backward, not downward. The anatomical neck of the humerus bone is located between the head and the greater and lesser tubercles, not separating them.

    Rate this question:

  • 8. 

    The spiral groove parallel to deltoid tuberosity, and lodges the radial nerve only.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false. The spiral groove does not only lodge the radial nerve, but it also lodges the deep brachial artery.

    Rate this question:

  • 9. 

    The lateral supraepicondylar ridge is more roughened, providing the site of common origin of the forearm extensor muscles. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The lateral supraepicondylar ridge is indeed more roughened, which makes it an ideal site for the common origin of the forearm extensor muscles. This roughness helps provide stability and strength to these muscles, allowing for efficient movement and control of the forearm. Therefore, the statement "The lateral supraepicondylar ridge is more roughened, providing the site of common origin of the forearm extensor muscles" is true.

    Rate this question:

  • 10. 

    The ulnar groove passes in a groove on the posterior aspect of the lateral epicondylar.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The ulnar groove does not pass in a groove on the posterior aspect of the lateral epicondyle. This statement is incorrect. The ulnar groove is actually located on the anterior aspect of the medial epicondyle of the humerus.
