Rhomboids – movers of the scapula
Among muscles, the rhomboids are very popular. Unfortunately, these muscles are often popular for the wrong reasons. They are often associated with upper back pain, particularly from sitting for prolonged periods as well as generalized postural problems. While, these muscles may be where you feel pain, it doesn’t mean that they are the source of that pain.
What does the name of the rhomboid muscle mean?
The rhomboid muscle is named for its shape. Specifically, the name comes from the Greek “rhombos”, which describes the angled parallelogram shape.
The rhomboids are part of the deep layer of muscles on the back and are located between the scapula and the spine. These muscles run deep to the trapezius, which means you’ll find them underneath the trapezius. Interestingly, they are sometimes referred to as the Christmas tree muscles due to their shape.
Based on their location, the rhomboids are divided into a major and minor portion which originate and insert in different places.

Where do the rhomboid muscles attach?
- You’ll find the origin of rhomboids major on the spinous processes of vertebrae T2-T5.
- Rhomboids minor, however, attaches on the spinous processes of vertebrae C7 and T1.
- Rhomboids major inserts on the vertebral border (edge closest to the spine) from the root of the spine to the inferior angle (bottom of the scapula).
- Rhomboids minor, however, inserts on the root of the spine of the scapula.
What actions do the rhomboid muscles do?
- These muscles retract the scapula, which means the scapula moves toward spine.
- Additionally, they also downwardly rotate the scapula, which means the top of the scapula tilts down and forward.
