Interstitial growth which includes. Two types of cartilage growth.

Expansion of the cartilage.

What are the two types of cartilage growth. Cells secrete matrix against external face of existing cartilage. Three main types of cartilage can be distinguished. Growth from the outside.

Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. In interstitial growth chondrocytes proliferate and divide producing more matrix inside existing cartilage throughout childhood and adolescence. In appositional growth fresh layers of matrix are added to existing matrix surface by chondroblasts in the perichondrium.

Hyaline cartilage has fewer cells than elastic cartilage. Describe appositional growth of cartilage. There are three types of cartilage.

In the embryo bone begins as hyaline cartilage and later ossifies. There are two types of ossification. In elastic cartilage the cells are closer together creating less intercellular space.

Chondrocytes divide isogenous groups a cluster of chondrocytes all formed through division of a single progenitor cell daughter cells produce matrix which pushes cells apart i e. Growth from the inside. Growth plates are areas of cartilage at the ends of the body s long bones.

Chondrocytes divide and secrete new matrix. Elastic a hyaline b and fibrous c. Growth of cartilage is attributable to two processes.

There is more intercellular space. Compare and contrast interstitial and appositional growth. Osteoblasts osteocytes and osteoclasts are the three cell types involved in the development growth and remodeling of bones.

Describe interstitial growth of cartilage. Synthesis of the extracellular matrix. Elastic cartilage is found in the external ear flaps and in parts of the larynx.

Hyaline fibrous and elastic cartilage. There are three different types of cartilage. Because the growth plates are the last portion of a child s bones to harden ossify they are particularly vulnerable to fracture.

Hyaline cartilage is the most widespread type and resembles glass. Cell division of the chondrocytes. Expanding cartilage from within.

Osteoblasts are bone forming cells osteocytes are mature bone cells and osteoclasts break down and reabsorb bone. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. Cartilage grows in two ways.

It persists in human adults at the ends of bones in free moving joints as articular cartilage at the ends of the ribs and in the nose larynx trachea and bronchi.
