4. The Lower Limb • The Femur • From the hip to the knee • The Patella (knee cap) • A sesamoid bone • Found in the tendon of the quadriceps muscle Femur Patella

5. The Lower Limb (continued) • Tibia and fibula • From the knee to the ankle, these are the leg bones • The fibula is lateral • The tibia is medial • Medial Malleolus and Lateral Malleolus • The distal ends of the two bones extend to the medial and lateral sides of the ankle • Commonly referred to as the ankle bones Fibula Tibia Lateral Malleolus Malléolemédiale

6. The Lower Limb (continued) The Tarsals • The tarsals make up the ankle bones • 7 bones total Tarsals

7. Tarsals Calcaneus Cuboid Lateral Cuneiform Talus Navicular Intermediate Cuneiform Medial Cuneiform

8. Metatarsals • Bones of the foot • 5 Bones in total • United with the toes Metatarsals 5 4 1 3 2

9. Phalanges • The great toe has only 2 phalanges • The other four have 3 phalanges Proximal phalanx of the 5th digit Middle phalanx of the 3rd digit Distal phalanx of the 1st digit (great toe)
