In human skeletal system. At the chest many rib bones connect to the sternum via costal cartilage segments of hyaline cartilage that allow the rib cage to expand during respiration. Building a cage true ribs.

Rib cage anatomy the rib cage shaped in a mild cone shape and more flexible than most bone sets is made up of varying elements such as the thoracic vertebra 12 equally paired ribs costal cartilage and held together anteriorly by the sternum. Anteriorly they continue as cartilage known as costal cartilage. The rib cage is collectively made up of long curved individual bones with joint connections to the spinal vertebrae.

In humans the rib cage also known as the thoracic cage is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton. In human skeletal system the bony thoracic basket or rib cage which forms the skeleton of the wall of the chest or thorax. Rib cage anatomy and breathing the ribcage is made to be flexible and springy so the lungs can fill and deflate easily the ribcage is like a large scale collapsible chicken carcass.

Although fixed into place these ribs do allow for some outward movement. A typical human rib cage consists of 24 ribs in 12 pairs the sternum and xiphoid process the costal cartilages and the 12 thoracic vertebrae. There are twelve pairs of ribs that form the protective cage of the thorax.

The rib cage the rib cage or thoracic basket consists of the 12 thoracic chest vertebrae the 24 ribs and the breastbone or sternum. The last two sets of ribs 11 and 12 are not attached to anything in. Its designed to move with respiration the ribs rising and lowering with each breath thus increasing the capacity of the chest cavity while reducing its pressure.

They are curved and flat bones.
