Anatomy of Femoral nerve

Summary of anatomy of femoral nerve.........

1. FEMORAL NERVE Ajith .C. B.P.T. Student-K.M.C.H . COPT , Coimbatore.

2. Introduction The femoral nerve is the chief nerve of the anterior compartment of the Thigh.

3. Origin And Root Value

4. Origin And Root Value Origin: It is formed by the dorsal divisions of the anterior primary rami of spinal nerves. Root Value: Spinal nerves L2, L3, and L4.

5. Course

6. Course It emerges at the 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)*

7. The nerve enter the 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 .

10. Branches And Distribution There are 4 branches in it. They are Muscular branches Cutaneous branches Articular branches Vascular branches

11. Muscular Branches The anterior division supplies the Sartorius Posterior division supplies the, Rectus femoris Vastus medialis , Intermediate and lateralis , Articular genu The Articular genu is supplied by a branch from the nerve vastus intermedius .

12. Cutaneus Branches The anterior division gives two cutaneous branches. they are, Medial cutaneous nerve of thigh Intermediate cutaneous nerve of thigh The posterior division gives only one cutaneous branch, the saphenous nerve.

13. Articular Branches The Hip joint is 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.

14. Vascular Branches The femoral artery and its branches.
