It’s a triangular muscle which occasionally peeps in the floor of the femoral triangle between pectineus and adductor longus.

Origin

It appears from the anterior outermost layer of the body of pubis and the outer surface of the inferior ramus of pubis in the period between the gracilis and the obturator externus.

Insertion

The muscle enters downward, backward, and laterally to be added along a line stretching from the lesser trochanter to the upper part of linea aspera, behind the pectineus and upper part of the adductor longus.

Nerve Supply

It’s normally provided by the anterior section of the obturator nerve but sometimes it can also be provided by the posterior section of the obturator nerve.
