    Action: Helps to flex and adduct arm
    Innervation: Musculocutaneous nerve (C5, C6 and C7)
  12. 12Pectoralis MajorOrigin: medial half of clavicle, sternum, cartilage of the true ribs 1-6, and the facia of the external oblique
    Insertion: Lateral lip of bicepital groove
    Action: Add and IR (THE SHOULDER) upper fibers flex the shoulder, lower fibers extend the shoulder.
    Innervation: Lateral and medial pectoral nerves; clavicular head (C5 and C6, sternocostal head (C7, C8, and T1
