Cartilage hyaline

The principal proteins of hyaline cartilage (the major type of cartilage) are Usted in Table 48—11. Type II collagen is the principal protein (Figure 48—13), and a number of other minor types of collagen are also present. In...

The bronchus is a tubular structure that brings air into the alveoli. It is lined with pseudostratified columnar epithelium surrounded by a thin lamina propria containing fine collagen and elastic fibers. A thin layer of smooth muscle surrounds the lamina propria. Glands are found in the submucosa and hyaline cartilage and the pulmonary arteries are found in the outer layer (adventitia).

Inhibitors of matrix metaloproteases also reside in normal hyaline cartilage, where they may inhibit vascular invasion [107]. Blood vessel invasion into cartilage induces endochondral ossification, a normal process in the growth of long bones, but which would be undesirable, for example, in the articular cartilage. Loss of angioinhibitory activity within articular cartilage may contribute to the vascular invasion and ossification, which characterizes the osteoarthritic joint [108, 109],...

The large volume occupied by high molecular size HA chains, including the aqueous solvent volume underlies the ability to distend and maintain extracellular spaces and tissue hydration. In fact, the moisture of skin is attributed to the rich HA content of the dermal compartment. For example, HA is present in significant amounts in hyaline cartilages, enough to fill the tissue volume in the absence of other constituents. Therefore, HA has been assigned various roles in the homeostasis of the extracellular space [17]. 

Joints form the sites where bones come together or articulate. Joints are classified by the type of tissue that lies between the bones. Joints with fibrous tissue between the articulating surfaces are called fibrous joints and include the sutures of the skull. Cartilaginous joints are united by hyaline cartilage and are classified into primary and secondary cartilaginous joints. Primary cartilaginous joints do not allow any movement.
