To be precise, it occupies the of the linea aspera. It sits between the attachments of the vastus medialis (anteriorly) and the adductor magnus and brevis (posteriorly). 3. Innervation and Blood Supply
The muscle originates from the .
The adductor longus muscle inserts into the linea aspera of the femur , which is a prominent ridge on the posterior surface of the femur (thigh bone). More specifically, it inserts into the middle third of the linea aspera. This insertion point allows the muscle to exert its pull on the femur, facilitating movements such as adduction, extension, and medial rotation of the hip joint. adductor longus origin and insertion
It is innervated by the obturator nerve (specifically the anterior division, roots L2, L3, and L4). To be precise, it occupies the of the linea aspera
The insertion site is deeply situated and not palpable externally, but it is a key landmark during posterior or medial surgical approaches to the femur. Innervation and Blood Supply The muscle originates from
The adductor longus muscle originates from the body of the pubis , specifically from the anterior surface of the pubis, near the symphysis pubis. This origin point is significant as it is one of the key muscles that arise from the pubic bone, contributing to the medial compartment of the thigh.
