distributed
• Types
–Connective tissue proper
–Cartilage
–Blood
–Bone
Functions
• Binding and support
• Protection
• Insulation

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 –
Gives rise to all
other connective
tissues
Only found in
