obturator externus

external obturator

Flat and triangular in outline, obturator externus covers the outer surface of the anterior wall of the pelvis and attaches to both the pelvis and the femur. It is classed among the adductor muscles by its action on the thigh, but its regional assignment is not settled in descriptive anatomy: it is sometimes considered part of the medial compartment of the thigh, and sometimes grouped with the gluteal region. That ambiguity follows from its position, since the muscle lies deep on the outer aspect of the pelvis at the boundary between the two territories. The Latin designation is external obturator, which distinguishes it from the internal obturator muscle lining the same foramen from within.
