Sternum or Breastbone: -

  • The sternum is a flat bone present just under the skin in the middle of the front of the chest. 
  • It is about 15 cm long. 
  • It consists of three parts— the manubrium is the uppermost part, the body is the middle portion and the xiphoid process is the tip of the bone. 
  • The true ribs (7 pairs) are attached to the sternum.
  • It protects the internal organs in the thoracic region. 
  • It also provides the surface for muscle attachment. 
  • The sternum helps in the respiratory mecha­nism.
