The pectineus muscle ( Latin for "comb muscle") is a muscle on the inside of the thigh . In animals, it limits the thigh triangle ( Trigonum femorale ) from behind. The pectineus muscle is united with the adductor longus muscle in ungulates and is part of the upper shell . Occasionally the fusion with the adductor longus muscle is also found in dogs .
The muscle flexes the hip joint , pulls the thigh toward the center of the body (adduction), and helps twist it outward. It is innervated by the femoral nerve and the anterior branch ( ramus anterior ) of the obturator nerve , which originate in the spinal cord segments L2 – L3 and L2 – L4.
