A rare muscular variation: the third of the rhomboids
During superficial back dissection of a 72-year-old male cadaver, an interesting aberrant muscle was observed bilaterallybelow the lower border of the rhomboideus major. The unusual muscle arose by a thin aponeurosis from the spinousprocesses of the mid-thoracic vertebrae and was attached laterally to the lowest part of the medial border of the scapula.Because of its characteristics the authors proposed the term – the third rhomboid (m. rhomboideus tertius)
