Hyaline cartilage is the most common kind of cartilage in the human body. [2] It is primarily composed of type II collagen and proteoglycans. [2] Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2]
A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. [1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage, and from synostosis (ossified junctions), which is the fusion of two or more bones.
Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline). [1] Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. Cartilaginous joints also forms the growth regions of immature long bones and the intervertebral discs of the spinal column.
In long bones, the secondary centers appear in the epiphyses. [2] At the end of the formation of the secondary ossification center, the only two areas where the cartilage remains is at the articular cartilage covering the epiphysis and at the epiphyseal plate between the epiphysis and diaphysis.

The bones that form the base and facial regions of the skull develop through the process of endochondral ossification. In this process, mesenchyme accumulates and differentiates into hyaline cartilage, which forms a model of the future bone. The hyaline cartilage model is then gradually, over a period of many years, displaced by bone.
The vomeronasal cartilage is a thin piece of hyaline cartilage that attaches to the vomer and extends to the septal nasal cartilage. [10] This structure is associated with the vomeronasal organ, which is part of the accessory olfactory system. This associated organ plays an important role in the sense of smell by being lined with similar ...
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
During the postnatal life, a secondary ossification center appears in each end of long bones. In these secondary centers, cartilage is converted to bone similarly to that occurring in a primary ossification center. [8] As the secondary ossification centers enlarge, residual cartilage persists in two distinct locations: [11]
