Which two back muscles share the same insertion point on the scapula?

Which two back muscles share the same insertion point on the scapula?

• A. Rhomboid Major and Rhomboid Minor
• B. Levator Scapulae and Serratus Anterior
• C. Latissimus Dorsi and Trapezius
• D. Infraspinatus and Teres Minor

Answer: (A)

The key idea is how a muscle’s insertion determines where it pulls. The rhomboid major and rhomboid minor both attach to the medial (vertebral) border of the scapula. Because they share this distal attachment, they pull the scapula medially toward the spine (retraction) and help hold it flat against the thorax, working together to stabilize the scapula. Other pairs don’t share that same insertion site on the scapula: one inserts at the superior angle or upper medial border, another on the anterior surface of the medial border, and others attach to the humerus or to different parts of the scapula (clavicle, acromion, spine) rather than the medial border. So the rhomboid major and rhomboid minor are the ones that share the same scapular insertion.
