Costal cartilages
Costal Cartilages
Costal cartilages (/ˈkɒstəl ˈkɑːrtɪlɪdʒ/; from Latin costa, "rib" and cartilago, "cartilage") are bars of hyaline cartilage that serve to prolong the ribs forward and contribute to the elasticity of the walls of the thorax.
Anatomy
The costal cartilages are parts of the skeletal system that connect the true ribs and false ribs to the sternum. They are located in the anterior chest wall, with one costal cartilage associated with each rib, providing structural support and flexibility.
Function
The primary function of the costal cartilages is to contribute to the elasticity and flexibility of the thoracic cage, allowing for the expansion and contraction of the chest during respiration.
