Average length : 16.94 in / 43.03 cm

The tibia also known as the shinbone or shankbone, is the larger and stronger of the two bones in the leg below the knee and it connects the knee with the ankle bones. In human anatomy the tibia is the second largest bone next to the femur.

The sternum or breastbone is a long flat bony plate shaped like a capital "T" located anteriorly to the heart in the center of the thorax (chest).
