-Hyaline cartilage is the most abundant in the body and surrounded by perichondrium. It is normally blue-white, smooth with a moist surface and turns yellow and becomes thinner in old age. It is found in nose, trachea, bronchi, ventral ends of ribs and sternal attachment. It provides a resilient, frictionless surface that resists compression at at sites of articulation. It is also found at epiphyseal growth plates.

 '''Chondrocytes'''
-Reside within '''lacunae''' within ECM and are responsible for synthesizing the '''matrix'''. The matrix consists of type II collagen, (except fibrocartilage) and proteoglycans with associated glycosaminoglycans. They are continually turned over and are the most vulnerable component of cartilage. Decresed proteoglycan, causes loss of lubrication which results in collagen disruption. This includes, frays, clefts, fibrillation, ulcers, exposure of bone, [[Musculoskeletal Terminology - Pathology|eburnation, +/- osteophytes and joint mice]].
