简要总结
Typically, the rhomboid minor muscles rise from the C7-T1 spinous process and run downward to touch the upper inner corner of the scapula, and the rhomboid major muscles rise from the T2-T5 spinous process and run downward to reach the lower middle inner corner of the scapula. In anatomical research articles, it has been reported that the rhomboid muscle's anatomical variations are rare. Considering the characteristics of these rhomboid muscles, the investigators planned a study on the utility of rhomboid muscles as a landmark for identifying thoracic spine levels.
