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. 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. Multifidus: attaches transverse processes together (ex. C3 and c4: attaches from spinous process to transverse process of another vertebrae, like rotatores but skips a vertebrae (c3 to c5) o o. Underneath layer, fibres run perpendicular- internal oblique muscle. All have aponeurosis = tendon, sheet, lengthy attachment, rarely attaches to bone.
