Pronuncation ROM-boids
Derivation Rhomboid- (diamond-) shaped. They are a grouping of rhomboid major and minor, so are referred to in the plural.
Origin Seventh cervical vertebra and thoracic vertebrae #1-5.
Insertion Medial border of scapula.
Action Draws the scapula toward the spine, and rotates its inferior angle medially.

Only a small portion of the rhomboids are directly visible under the skin; most of the muscle lies under trapiezius. When tensed, one can see it as a curve sweeping upward from the inferior angle of the scapula, crossing the line of trapezius at what could be thought of as a mirror-image of the angle.
