The adductor longus, a muscle of the medial compartment of the thigh, is triangular in shape and forms in the floor of the femoral triangle and adductor canal. The muscle originates from the anterior surface of the body of the pubis, inferior to pubic crest and lateral to the pubic symphysis.
Insertion. Expands into a fan shape, attaching broadly to the linea aspera on the middle third of the femur. [1] This insertion point is between the insertion of the adductor magnus and the origin of the vastus medialis muscle, and inferior to the adductor brevis insertion. [2] muscle insertion. other muscle.
Adductor longus. Origin. Anterior surface of body of pubis, just lateral to pubic symphysis. Insertion. Middle third of linea aspera, between the more medial adductor magnus and brevis insertions and the more lateral origin of the vastus medialis. Action.
It is a large, flat muscle which partially covers the adductor brevis and magnus. Attachments: Originates from the pubis bone of the pelvis and expands into a fan shape. It has a broad distal attachment along the linea aspera of the femur. Actions: Adduction of the thigh. Innervation: Obturator nerve (L2-L4).
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.
Because the origin of the adductor longus is anterior to its insertion, its contraction also causes a slight flexion and medial rotation in the thigh. Explore Innerbody's 3D anatomical model of the adductor longus muscle, one of the major muscles of the groin.
Insertion. The fibers of the adductor longus muscle travel inferolaterally and insert, via a broad aponeurosis, onto the middle one third of the linea aspera of the femur.
Origin. The Adductor Longus originates from the anterior surface of the pubis bone, just below the pubic crest and near the pubic symphysis. This origin point places it in a strategic position for influencing movement at the hip joint. Insertion
Origin: The adductor longus muscle originates from the pubic bone, specifically from the pubic crest, which is a ridge on the superior border of the pubic bone. Insertion: The muscle inserts into the middle third of the linea aspera, a ridge on the posterior surface of the femur (thigh bone).
