M. obturator internus ( fig. 15 )

ORIGIN: From the medial surface of the anterior half of the horizontal ramus of the pubis.

INSERTION: Via a flat tendon that runs through the sciatic notch and over the dorsal margin of the acetabulum, superficial to M. gemellus , to insert on the posteroproximal surface of the greater trochanter of the femur.

REMARKS: This muscle has the same general form in Condylura , Neurotrichus , Parascalops , Scalopus , Scapanus , Scaptonyx , Talpa , Uropsilus , and Urotrichus . This muscle is apparently absent in Desmana and Galemys . Dobson (1882–1890) also noted the absence of this muscle in Desmana .
