The obturatorius externus is a flat triangular muscle covering the wall of the pelvis. It originates from the lower half of the obturator foramen. The muscle fibres converge into a tendon which runs across the back of the hip joint and inserts in the femur. It is innervated by the obturator nerve and supplied by the obturator artery and the internal circumflex artery. This muscle rotates the femur outward.
 Research Obturator Externus
The obturator foramen is the large opening in each pubis. These openings admit blood vessels and nerves from the abdominal cavity to the inside of the upper legs.
Research Obturator Foramen
The obturatorius internus lies partly within the cavity of the pelvis and partly at the back of the hip joint. It originates from the margin of the obturator foramen and narrows into a single, flattened tendon at its point of insertion in the great trochanter of the femur. This muscle is innervated by the sacral plexus and supplied bythe inferior gluteal artery. It helps rotate the thigh and steady it when sitting up.
