quadratus lumborum iliac crest and iliolumbar ligament inferior border of rib 12 and first 4 lumbar vertebrae acting together, pull 12th ribs inferiorly during forced exhalation; fix 12th ribs to prevent their elevation during deep inhalation, help extend lumbar portion of column, acting singly, laterally flex vertebral colums, especially lumbar portion thoracic spinal nerve T12, and lumbar spinal nerves L1-L3or L4
Latissimus dorsi spines of inferior 6 thoracic vertebrae, lumbar vertebrae, crests of sacrum and ilium, inferior 4 ribs intertubercular sulcus of humerus extends adducts, and medially rotates arm at shoulder, draws arm inferiorly and posteriorly thoracodorsal
levator scapula superior 4 or 5 cervical vertebrae superior vertebral border of scapula elevates scapula and rotates it downward dorsal scapular nerve and cervical spinal nerves C3-C5
subclavius first rib clavicle depresses and moves clavicle anteriorly and helps stabilize pectoral girdle subclavian nerve
serratus anterior superior 8 or 9 ribs vertebral border and inferior angle of scapula ABDUCTS scapula and rotates it upward, elevates ribs when scapula is stable, "boxer's muscle" long thoracic nerve
pectoralis major clavicle, sternum, costal cartilages of ribs 2-6 greater tubercle and lateral lip of the intertubercular sulcus of humerus as a whole, adducts and medially rotates arm at shoulder, clavicular head also extends the flexed arm to side of trunk medial and lateral pectoral nerves
pectoralis minor ribs 2-5, 3-5, or 2-4 coracoid process of scapula ABDUCTS scapula and rotates it downward, elevates ribs during forced inhalation when scapula is fixed medial pectoral nerve
diaphragm xiphoid process of sternum, costal cartilages inferior 6 ribs, lumbar vertevrae and their discs, and rib 12 central tendon contraction causes it to flatten and increase the vertical dimension of the thoracic cavity, resulting in inhalation; relaxation causes it to move superiorly and decreas dimension, result is exhalation phrenic nerve
