Idenify muscular compartments: vertebral muscles, abdominal muscles c. Breathing" muscles: perineum and pelvic diaphragm muscles, within each compartment idenify, muscular atachments, common nerve supply, muscular funcion. Erector spinae, it consists of three muscles keeps the spine erect: iliocostalis. Ataches from the iliac crest of the hip and expands out across the back to the ribs on the angles of the ribs on the back of the rib cage: longissimus. Inserion point is to all the transverse processes of the lumbar, thoracic, and cervical vertebrae: spinalis. Ataches to the spinous process of the back: lumbar, thoracic and cervical spinous processes: there is a fascia known as the thoracolumbar fascia (white part) that holds a common origin point to all three muscles. Iliocostalis has origin on both the iliac crest and the thoracolumbar fascia. The longissimus and spinalis truly come of of the thoracolumbar fascia r.
