The muscles of the back include those that move the vertebral column, help maintain posture, and are involved in movements of the pectoral (shoulder) girdle and arm.
For classification purposes, the muscles of the back can be arbitrarily divided into two distinct groups:
- intrinsic muscles of back;
- extrinsic muscles of back.
The intrinsic muscles lie deep to the thoracolumbar fascia, while the extrinsic muscles lie superficial to it.
