What is the origin of the rhomboid major?

Explanation:
The key idea is knowing where the rhomboid major sits on the spine and which vertebral levels feed its origin. The rhomboid major originates from the spinous processes of the upper thoracic vertebrae, specifically from T2 to T5. From there, its fibers run laterally to insert along the medial border of the scapula, helping to retract and downwardly rotate the scapula. This area (T2–T5) distinguishes it from the rhomboid minor, which comes from C7 to T1, and from origins on transverse processes, which belong to other muscles. So the T2–T5 spinous processes accurately describe the rhomboid major’s origin.
