DETAILS: Made of a group of 3 muscles that are bundled together (9 muscles in total) that run vertically down the vertebral column
FUNCTION: Stabilization of the spine, extension, lateral flexion (side bending) and rotation of the back. Unilateral (one-sided) contraction of the erector spinae group causes the same flexion (ipsilateral) or rotate, while bilateral contraction extends a portion of the spine.
