What is cartilage made of?
Cartilage Meaning. Cartilage is a connective tissue that is composed of unique and specialized cells called chondrocytes. Chondrocytes are responsible for turning over the large collection of material that composes the extracellular matrix.
How do chondroblasts form?
As an embryo, chondroblasts form through a process called chondrification within a collection of unspecialized cells collectively known as the mesenchyme. Cartilage is avascular and receives its nutrients from a nearby connective tissue caller perichondrium. There are three types of cartilage: Hyaline cartilage.
Why is cartilage repair slower than other tissue types?
This also means that cartilage repairs much slower than other tissue types. Diffuse replenishes nutrients at a lower rate than what can be delivered by vessels and so cartilage receives the material needed to repair much slower than skin or bone. Repair of cartilage is also limited by the extracellular matrix. Because the chondrocytes are responsible for producing the material that composes cartilage, they must be within the area of damage to produce new needed material. However, chondrocytes are trapped within this matrix and cannot migrate to new areas.
Why is cartilage avascular?
Recall that cartilage is avascular. This means that it cannot receive nourishment to grow and repair from vessels like other tissue types. Instead, it must rely on diffusion. Nutrients diffuse across cartilage from capillaries observed in the perichondrium. The perichondrium is a type of connective tissue that surrounds cartilage and aids in repair and growth. Because cartilage depends on diffusion to maintain its nutrient requirements, it makes sense that it remains relatively thin throughout the body. A thick piece of tissue would be unable to diffuse nutrients throughout its entire volume.
