The tibia & fibula are the bones we focused on during week 4.
The tibia or shinbone is the larger and stronger of the two bones in the leg below the knee and connects the knee with the ankle bones.
The fibula or calf bone is a bone located on the lateral or outside of the tibia with which it is connected above and below. It is the smaller of the two bones in the leg below the knee. It forms the lump just above and to the outside of the foot, this lump is called your ankle bone.
