attchments, actions, innervation and spinal cord segments of: pectoralis major
bony attcchments:
* sternocostal: costal cartilages and sternum TO lateral lip intertubercular salcus
* clavicular: clavical TO lateral lip intertubercular sulcus
action: humeral adduction, flexion & internal rotation (sternocostal = extension of flexed arm)
innervation: lateral (sternocostal) and medial (clavicular) pectoral n
spinal cord: clavicular = 5-7, sternocostal = C8-T1
