Hyaline cartilage
Hyaline cartilage is the most prevalent type, forming articular cartilages and the framework for parts of the nose, larynx, and trachea. This image shows a cross section of a cartilage ring that supports the trachea and maintains the openness (patency) of the airway. The lumen of the trachea is at the bottom. 100x
![Hyaline cartilage > <p>Visible in this low magnification image of hyaline cartilage, are numerous cells embedded in the matrix. Many of the cells are in isogenous units. Hyaline cartilage undergoes regressive changes, a process that is visible in the center of the cartilage. Surrounding the cartilage, is a border of connective tissue called the perichondrium. This two-layered covering serves as protection for the cartilage and is a source of the chondroblasts that lie on the cartilage surface.</p>](https://digitalhistology.org/wp-content/uploads/2022/06/T.C.C.H.01-1-ping.png)
