- origin: broad aponeurosis that originates on the spinous processes
of the lower 6 thoracic and all lumbar vertebrae; posterior crest
of ilium, posterior surface
of sacrum, lower 3 or 4 ribs, and an
attachment of the tip of the scapula;
- insertion: flat tendon that twists upon itself to insert into the
intertubercular groove of the humerus, just anterior to and
parallel with the tendon of
pectoralis major;
- nerve supply: thoracodorsal from
brachial plexus,
C6, C7,
C8;
- action: extends, adducts and medially rotates the humerus at the
shoulder; draws the inferior angle of the scapula inferior and
medial; (draws shoulder downward and backward);
- synergists: rhomboids,
pectoralis major, teres major;
