Adductor Longus Origin And Insertion ((full)) Jun 2026

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.

| Feature | Detail | |----------------|-------------------------------------------------------------------------| | | Anterior body of the pubis (inferior to pubic tubercle) | | Insertion | Middle third of the medial lip of the linea aspera (femur) | | Nerve | Obturator nerve (anterior division, L2–L4) | | Blood Supply | Deep femoral artery (profunda femoris) and medial circumflex femoral artery | | Primary Action | Hip adduction, assists with hip flexion and medial rotation | adductor longus origin and insertion

It receives oxygenated blood primarily from the deep femoral artery (profunda femoris) and the obturator artery. 4. Primary Functions The insertion site is deeply situated and not

Specifically, it attaches to the body of the pubis, just inferior to the pubic crest and lateral to the pubic symphysis. Unlike some deeper muscles that have broad, fleshy attachments, the adductor longus begins as a strong, narrow tendon that is easily palpable in the groin area. Primary Functions Specifically, it attaches to the body

The adductor longus muscle is one of the three adductor muscles, along with the adductor brevis and adductor magnus. While these muscles share similar functions, their specific origins, insertions, and innervations may vary. For instance, the adductor magnus muscle has a dual innervation, receiving both obturator and tibial nerve innervations, whereas the adductor longus is primarily innervated by the obturator nerve.
