                    - Obturator Internus
                    - Gemellus Inferior

           - Obturator Externus
           - Quadratus Femoris
           - Gluteus Maximus


    - the external rotators arise from pelvic surface of sacrum & from hip bone & insert on or about greater trochanter (w/ the exception 
           of the maximus);
    - the superior and inferior gemelli join together along with the obturator internus to form the conjoined tendon;
