|Anatomical terms of muscle|
In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle.
Origin and insertion
It lies ventrally on the adductor magnus, and near the femur, the adductor brevis is interposed between these two muscles. Distally, the fibers of the adductor longus extend into the adductor canal.
Its main actions is to adduct and medially rotate the thigh; it can also produce some degree of flexion/anteversion.
As part of the medial compartment of the thigh, the adductor longus is innervated by the anterior division (sometimes the posterior division) of the obturator nerve. The obturator nerve exits via the anterior rami of the spinal cord from L2, L3, and L4.[not in citation given]
