A winged scapula
Correct Answer
E. A winged scapulaExplanation
A winged scapula can be caused by a lesion of the nerve that supplies the tagged muscle. This is because the winged scapula refers to the abnormal protrusion or prominence of the scapula bone, which can occur when the muscles that stabilize the scapula are weakened or paralyzed due to nerve damage. Therefore, a winged scapula can be a manifestation of a nerve lesion affecting the muscles involved in scapula stabilization.Rate this question:
