Study Notes
Rhomboid Major Muscle
- Origin: Spines of thoracic vertebrae T2 to T5.
- Insertion: Inferior medial border of the scapula, specifically between the scapular spine and the medial border.
- Action:
- Primarily retracts the scapula (pulling it medially towards the spine).
- Also rotates the scapula, contributing to downward rotation.
- Innervation: Dorsal scapular nerve.
