Presentation Transcript

  1. Lower Limb

  2. Thigh • Knee • Leg • Ankle • foot

  3. thigh • Femur articulates with • Acetabulum to form hip joint • Tibia and patella to form knee joint

  4. Fascial compartments of thigh • Anterior compartment • Major muscle : quadriceps femoris • Femoral artery • Femoral nerve • Extension of leg at knee joint • Flexes thigh at hip joint

  5. Posterior compartment: • Biceps femoris • Branches of profundafemoris artery • Sciatic nerve

  6. Medial fascial compartment: • Major muscle:Adductormagnus • Profundafemoris artery and obturator artery • Obturatornerve

  7. Patella • Largest sesamoid bone(within quadriceps femoris muscle ) • Triangular bone with apex facing downward • articulates with the femur • covers and protects the anterior articular surface of the knee joint.

  8. tibia • Large weight bearing medial bone of the leg • Articulates with the condyles of the femur and the head of the fibula above and • with the talus and the distal end of fibula below

  9. fibula • Slender lateral bone of the leg. • No articulation at knee joint, • Articulates with the tibia above and below

  10. Poplitealfossa • Diamond shaped intramuscular space situated at the back of the knee joint • Laterally: biceps femoris above and lateral head of gastrocnemius and plantaris below • Medially: medial had of gastrocnemius • Contains nerves and blood vessels passing between leg and thigh

  11. Anterior fascial compartment of leg • Tibialis anterior • Anterior tibial artery • Deep peroneal nerve • Dorsiflexion of foot at ankle ,inverts the foot

  12. lateral fascial compartment of leg • Peroneuslongus • Branches from peroneal artery • Superficial peroneal nerve • Plantar flexes the foot at ankle

  13. posterior fascial compartment of leg • Gastrocnemius, plantaris • Posterior tibial artery • Tibial nerve • Plantar flexes the foot at ankle and flexes the knee.

  14. We have tarsal bones forming the heel of the foot • Metatarsals forming the middle portion of the foot • And • Phalanges forming the toes
