Detailed explanation-1: -The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.
Detailed explanation-2: -The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
Detailed explanation-3: -The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.
Detailed explanation-4: -During inspiration, the anteroposterior diameter of the thorax is increased when the ribs are raised. Because ribs slope downward, any elevation during inspiration results in an upward movement of the sternum at the manubriosternal joint and an increase in the anteroposterior diameter of the thorax.
