Origin: Pubic body just below the pubic crest
Insertion: Middle third of linea aspera
Artery: Obturator artery
Nerve: Anterior branch of obturator nerve
Action: Adduction of thigh
The Adductor longus, the most superficial of the three Adductores, is a triangular muscle, lying in the same plane as the Pectineus. It arises by a flat, narrow tendon, from the front of the pubis, at the angle of junction of the crest with the symphysis; and soon expands into a broad fleshy belly. This passes downward, backward, and lateralward, and is inserted, by an aponeurosis, into the linea aspera, between the Vastus medialis and the Adductor magnus, with both of which it is usually blended.
