  The femoral nerveis the chief nerve of the anterior compartment of the Thigh.
• 4.
  Origin: It isformed by the dorsal divisions of the anterior primary rami of spinal nerves. Root Value: Spinal nerves L2, L3, and L4.

  It emerges atthe lateral border of psoas major muscle in abdomen .it passes downwards between psoas major and illiacus muscles. It gives branches to Pectineus muscle, which passes behind the femoral sheath to reach the muscle. (Note:- Pectineus muscle are supplied by both are Femoral and Obturator nerve)*

  The nerve enterthe thigh behind the inguinal ligament , lateral to femoral sheath. It is not content of femoral sheath as its formation is behind fascia illiaca. It will dividing 2.5cm below the inguinal ligament .in between two divisions , lateral circumflex femoral artery is present .

  There are 4branches in it. They are 1. Muscular branches 2. Cutaneous branches 3. Articular branches 4. Vascular branches

  The anterior divisionsupplies the Sartorius Posterior division supplies the, i. Rectus femoris ii. Vastus medialis, Intermediate and lateralis, iii. Articular genu The Articular genu is supplied by a branch from the nerve vastus intermedius.

  The anterior divisiongives two cutaneous branches. they are, i. Medial cutaneous nerve of thigh ii. Intermediate cutaneous nerve of thigh The posterior division gives only one cutaneous branch, the saphenous nerve.

  The Hip jointis supplied by the nerve to rectus femoris The knee joint from branches to vasti. What is HILTON”S Law? This law stages the nerve supplying the joint also supplies the Muscles acting an that joint and also the skin covering (or) around the joint.
