Muscular group of the dorsal spine that originates at the sacrum, ilium, and lumbar vertebrae and attaches at the ribs and upper thoracic vertebra; the function is to maintain upright posture and extend the vertebral column.<\/p>\n

Three vertical bands of back muscles: the iliocostalis, longissimus, and spinalis.
