Document Summary
Identify muscular compartments: vertebral muscles, abdominal muscles c. Breathing muscles perineum and pelvic diaphragm muscles d: within each compartment identify, muscular attachments, common nerve supply, muscular function. Functions include ability to stand upright, posture, respiration, support vertebral column. Erector spinae muscles i like standing muscles 3 muscle acronym. Common origin: white diamond on diagram: no muscle tissue, just fascia (thoracial lumbar fascia, blood will settle in this region, bruise. Ilio = ileum o: costalis = ribs, o: from iliac crest and thoracial lumber fascia, spans out across the back o. I: attaches to angle of ribs: o: thoracial lumbar fascia o. I: transverse processes of lumbar, thoracic and cervical vertebrae. Roots off spinal cord, roots come together to form rami. Ventral is motor- stimulates skeletal muscle to cause it to contract. Doral is sensory- back into spinal cord. Majority of innervation to a muscle comes from the ventral rami. Excluding deep back muscles innervated by the dorsal rami o.
