Hyaline cartilage consists of a homogenous bluish ground substance with considerable degree of lacunae containing chondrocytes.  The chondrocyte has branching processes and they are sometimes two in number within a lacunae. They are large, having a central or sometimes eccentric nuclei with prominent nucleolus.

Their fibrous basis consists of fine fibers which resemble collagenous fibers  in nature. Their distinguishing feature is the presence of a covering known as perichondrium which is a dense connective tissue demonstrable by special stain. They have a system of cartilage canals or canaliculi which help to transport small arteries and veins into the deeper portions of the cartilage tissue. These canals have a definite pattern of arborisations and they are responsible for the nutrition of the cartilage tissue which are  relatively avascular tissues when compared to other connective tissues. There are two different types of hyaline connective tissues in adults.

1.  Articular hyaline cartilage which is found in the coverings of the bones in diarthrodial (synovial) joints. They are not covered with perichondrium. The surface cells are usually flattened and have numerous chondrocytes. This layer is followed internally by vertically disposed large chondrocytes which are not numerous.

2.  Costal cartilage is another type of hyaline cartilage. It is found in the ribs and the xiphoid process and it is morphologically similar to the cartilages of the larynx, pharynx, trachea and the major bronchi.

The fibers of hyaline cartilage are sometimes banded as in collagenous fibers and under the electron microscope they show 640oA periodicity.
