The semispinalis dorsi (or semispinalis thoracis) consists of thin narrow fleshy fasciculi interposed between tendons of considerable length. It arises by a series of small tendons from the transverse processes of the sixth to the tenth thoracic vertebrae and is inserted by tendons into the spinous processes of the upper four thoracic and lower two cervical vertebrae.
