Adductor Longus - Muscle Physiology & Functional Anatomy

Adductor Longus

 

Anatomy

 

Origin:

  • Body of pubis inferior & medial to pubic tubercle

Insertion:

  • Lower two thirds of medial linea aspera



Major Artery:

  • Obturator artery

 

Neural Innervation:

  • Anterior division of obturator nerve (L2-L3)

 

Trigger Points:

Adductor Magnus Longus Trigger Points   

 

 

Physiology

 

Concentric Functions:

  • Hip adduction, transverse adduction, & (initial) flexion

 

Eccentric Functions:

  • Decelerates hip abduction, extension & external rotation

  • Helps decelerate hip flexion at heel strike along with the other muscles of the adductor complex

 

Isometric Function:

  • Helps dynamically stabilize the lumbo-pelvic hip along with the other muscles of the adductor complex

More Information about the Adductor Longus Muscle

The adductor longus muscle is part of the adductor complex of the inner thighs.  It functions as a synergy with the adductor magnus, adductor brevis, & pectineus muscles to adduct the hip.  The adductor complex dynamically stabilizes the lumbo-pelvic hip complex during functional movements.
