     A 20-year-old male was shot at close range during a robbery attempt. The bullet penetrated his axillary region, damaging the two tagged structures. The patient will have difficulty performing which of the following actions? - ProProfs

     A 20-year-old male was shot at close range during a robbery attempt. The bullet penetrated his axillary region, damaging the two tagged structures. The patient will have difficulty performing which of the following actions?

    • Medially rotating and flexing the arm

    • Laterally rotating and abducting the arm

    • Retracting and inferiorly rotating the scapula

    • Medially rotating and adducting the arm

    • Supinating and flexing the forearm

    Correct Answer
    A. Medially rotating and adducting the arm
    Explanation
    The axillary region is located in the armpit and contains important structures such as the axillary nerve and the posterior circumflex humeral artery. Damage to these structures can result in weakness or loss of function in the muscles that medially rotate and adduct the arm, such as the latissimus dorsi and teres major muscles. Therefore, the patient will have difficulty performing these actions.

    Rate this question:

  • 6. 

     Which of the following structures is NOT in close contact with the tagged structure? (Use Q6 Tag)

    • Lateral cord of brachial plexus

    • Axillary artery

    • Posterior cord of brachial plexus

    • Medial pectoral nerve

    • Medial cord of brachial plexus

    Correct Answer
    A. Posterior cord of brachial plexus
    Explanation
    The question asks which structure is NOT in close contact with the tagged structure. The tagged structure is not specified in the question, but based on the options given, it can be inferred that the tagged structure is the axillary artery. The axillary artery is in close contact with the lateral cord, posterior cord, medial pectoral nerve, and medial cord of the brachial plexus. Therefore, the structure that is NOT in close contact with the axillary artery is the posterior cord of the brachial plexus.

    • Circumflex scapular

    • Deep artery of the arm

    • Dorsal scapular

    Correct Answer
    A. Dorsal scapular
    Explanation
    The tagged artery forms an anastomosis with the dorsal scapular artery.
