Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.
<h3>What is hyaline cartilage?</h3>
On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.
Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.
