Document Summary

Idenify muscular compartments: vertebral muscles, abdominal muscles, breathing muscles, perineum and pelvic diaphragm muscles, within each compartment idenify: Comes of of the ilium all the way up the ribs: longissimus. In series or bunches; goes across enire back (essenially) Ataches to all the transverse processes of vertebral column. Originates from triangular fascia on back -> known as thoracolumbar fascia= like a wide tendon; irregular dense connecive issue; purple triangle in back (purple bruise); atachment for a lot of structures: spinalis. Inferiorly also touches down the thoracolumbar fascia and superiorly ataches to all the spinous processes. Each muscle split up into regions (only focus on these 3) True back muscles: truly dedicated to erect the spine. Upright posiion, when standing sill the muscles are relaxed because all vertebrae are rested on top of one another. When move/bend over= where these muscles take on their role; controlled movements. Diferent than skeletal muscles= involved when moving but are innervated diferently.
