The adductor longus is a long, triangular muscle in the medial compartment of the thigh. It is the most superficial of the adductor group and forms part of the medial boundary of the femoral triangle.
Origin
Its fibres originate from the body of the pubis, specifically the anterior surface of the pubis inferior to the pubic crest and lateral to the pubic symphysis.
Insertion
The adductor longus fibres insert into the middle third of the linea aspera on the posterior surface of the femur, between the attachments of the adductor magnus and vastus medialis.
Actions
