Adductor brevis

The adductor brevis is a muscle in the thigh situated immediately behind the pectineus and adductor longus. It is somewhat triangular in form, and arises by a narrow origin from the outer surfaces of the superior and inferior rami of the pubis, between the gracilis and obturator externus. Its fibers, passing backward, lateralward, and downward, are inserted, by an aponeurosis, into the line leading from the lesser trochanter to the linea aspera and into the upper part of the linea aspera, immediately behind the pectineus and upper part of the adductor longus.[WP].
