Answer
Latissimus dorsi originates T6-T12, thoracolumbar fascia, iliac crest; inserts humerus groove; extends, adducts, medially rotates humerus; innervated by thoracodorsal.
The latissimus dorsi originates from the spines of T6-T12, thoracolumbar fascia, and iliac crest. It inserts into the intertubercular groove of the humerus, and its action is to extend, adduct, and medially rotate the humerus. It is innervated by the thoracodorsal nerve.
