POSTERIOR DIVISION OF OBTURATOR NERVE

 

ORIGIN: Lumbar plexus, roots L2-4

COURSE/DISTRIBUTION: This is one of the two terminal branches of the obturator nerve. It pierces the oburator extenus and supplies it and then passes behind the adductor brevis to reach the front of the adductor magnus. It then provides filaments to supply the knee joint which then pierces the adductor magnus to reach adductor magnus and perforates it in order to end af the back of the knee at the popliteal fossa. It descends on the popliteal artery and supplies it to reach the back of the knee.

 

BRANCHES:  Branches are

bulletMuscular branches to adductor magnus
bulletMuscular branches to adductor brevis when it is not supplied by the anterior division of obturator nerve
bulletArticular branches to knee joint
bulletFilaments to popliteal artery

ROOT VALUE: L2-4.
