I / Skeletal Connective Tissue
Cartilage & Bone called supporting connective tissue because they provide astrong and supporting into they body , in these connective tissue , the matrix contain numerous fibers and in some cases , deposits of insoluble calcium salts.
A- Cartilage : It form the skeleton of early mammalian fetuses but it is gradually replaced in the growing by bone matrix of cartilage is firm but pliable . It is composed of amorphous ground substance , fibers and characteristics cells .
Cartilage is surrounding by connective tissue region called perichondrium which composed of tow distinct layer- anouter , fibrous region of dense irregular connective tissue and an inner cellular (chondrogenic) layer composed of chondorogenic cell.Chondrogenic cell , found in the inner layer of the perichondrium differentiate into chonroblasts which produce cartilage . Condrocytes (matured chondoblasts) is single or group which formed cell nests; chondrocytes is located in the cavities called lacunae .there are three type of cartilage.
