In the body, the adductor longus is a skeletal muscle situated in the thigh. Among the adductor muscles of the hip, its primary function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle.

The adductor longus occurs from the superior ramus of the pubis.

It lies ventrally on the adductor magnus, and near the femur, the adductor brevis is interposed in between these 2 muscles. Distally, the fibers of the adductor longus extend into the adductor canal.

It is inserted into the middle third of the medial lip of the linea aspera.

The adductor longus remains in relation by its anterior surface with the pubic part of the fascia lata, and near its insertion with the femoral artery and vein.

By its posterior surface with the adductor brevis and magnus, the anterior branches of the obturator artery, vein, and nerves, and near its insertion with the profunda artery and vein.

By its external border with the pectineus, and by the inner border with the gracilis.

Its primary actions is to adduct and laterally turn the thigh; it can likewise produce some degree of flexion/anteversion.

As part of the medial compartment of the thigh, the adductor longus is innervated by the anterior department (often the posterior department) of the obturator nerve. The obturator nerve exits by means of the anterior rami of the spine from L2, L3, and L4 [stopped working confirmation]
Adductor longus is stemmed from the myotome of spinal roots L2, L3, and L4.
