GROUND SUBSTANCE
Consist of : - glycoproteins
- proteoglycansColorless and transparant.Fills the space between cells and fibers .

LOOSE CONNECTIVE TISSUE
Support many structures that are normallyunder pressure and low friction.Consist of all the main component ofconnective tissue proper.The most numerous cells are fibroblasts andmacrophages, but all the other types ofconnective tissue cells are also present.

DENSE CONNECTIVE TISSUE
Consist of the same components found in looseconnective tissue, but there are fewer cells andclear predominant of collagen fibers.Less flexible and far more resistant to stress
There are dense irregular and regular

ELASTIC TISSUE
Compound of band less thick, parallel elasticfibers.Occurs infrequently
Present in the yellow ligaments of the vertebralcollumn and in the suspensory ligament of the
penis.

RETICULER TISSUE
Consist of reticular fibers intimally associatedwith specialized fibroblasts called reticularcells.At the hematopoietic organs and lymphoidorgans.

MUCOUS TISSUE
Found mainly in the umbilical cord= Whartons Jelly Has an abundance of ground substancecomposed chiefly of hyaluronic acid. Its jellylike tissue containing very few fibers.Also found in the pulp of young teeth.
