CONNECTIVE TISSUE
Connective Tissue Most abundant and widely distributed Types –Connective tissue proper –Cartilage –Blood –Bone
Functions Binding and support Protection Insulation Transportation
Marfan’s syndrome
Elhers-danlos
Characteristics -Varying degrees of vascularity -Varying degrees of cellularity -Extracellular matrix- contains ground substance and fibers
Ground substance – interstitial fluid, adhesion proteins, proteoglycans (protein core with GAGS – glycosaminoglycans) Fibers – collagen elastic reticular Cells –
Gel like Star shaped Gives rise to all other connective tissues Only found in embryos
