- vastus lateralis

vastus medialis
Apex
ligamentum patellae
Base
quadriceps femoris
- Known as kneecap, is a thick, circular-triangular bone which
articulates with the femur and covers and protects the anterior
articular surface of the knee joint. It is the largest sesamoid
bone in the human body.

9. FEMORAL NERVE

10. FEMORAL NERVE
-Nerve of the anterior or extensor compartment of the
thigh
-Posterior divisions of anterior rami of L2,3,4
-At midpoint of inguinal ligament, deep to it and lateral to
femoral vessels
-It breaks up into terminal branches at one inch below the
ligament

11. OBTURATOR NERVE

12. OBTURATOR NERVE
Anterior divisions of anterior rami of L2,3,4
BRANCHCES
1. From Trunk
- To Obturator externus
2. From anterior division
- Articular branch to hip joint
-To adductor longus, gracilis, pectineus
-Cutaneous branch communicate with medial
- cutaneous nerve of thigh & saphenous nerve
-To form subsatorial plexus
3.From posterior division
-To adductor brevis, obturator externus
& adductor magnus
-To knee joint

13. SCIATIC NERVE
-Ventral rami of L4,5,S1,2,3
-Branches in Thigh
-To hamstrings & adductor magnus (Tibial)
-Biceps (Common Peroneal Nerve)
-Danger side at Medial side

15. COMMON PERONEAL NERVE

16. COMMON PERONEAL NERVE
-lateral and smaller of the two terminal branches
-arises from the posterior divisions of the sacral plexus
(L4 to S2)
-begins at the superior angle of the popliteal fossa
-winding around the lateral surface of the neck of the
fibular and ends by dividing into superficial & deep
peroneal nerves in the substance of peroneus longus
muscle

17. TIBIAL NERVE
-Medial terminal branch
-arises from the anterior diovisions of the sacral plexus
(L4 to S2)
-Repressents the main continuation of the sciatic nerve
