Introduction[edit | edit source]
Cartilage is a type of supporting connective tissue . It is a firm tissue but softer and more flexible than bone .
Cartilage Structure [edit | edit source]
cartilage matrix | cartilage cells |
it is a firm gel that contain polysacchride derivaites called chondroitin sulfates which complex with protein in the ground substance forming proteoglycan . | chondrocytes are the only cells in the matrix and they occupy small chambers called lacuna . |
- Cartilage separated from the surrounding tissues by perichondrium which consist of two layers :
1- Outer Fibrous Layer : Which provide protection , mechanical support and attaches the cartilage to other structures .
2- Inner Cellular : It Is Important in the growth and maintenance of cartilage .
Cartilage types[edit | edit source]
Hyaline cartilage | fibrocartilage | elastic cartilage |
The matrix contain closely packed collagen fibers making it tough but slightly flexible . Example : Connection between ribs and sternum , nasal cartilage and articular cartilage ( which cover opposing bone surfaces in many joints ) . |
The matrix contain interwoven collagen fibers making it durable and tough . Example : between spinal vertebrea and around the joints . |
The matrix contain elsatic fibers making it flexible and reselient . Example : the auricle of the outer ear . |
