Connective Tissue proper

Loose and dense

Loose

Adipose and areolar

Dense

Regular and irregular

Specialized connective tissue

Cartilage bone blood

Adipose

Cells filled with fat (energy storage, insulation, cushioning)

Areolar

Binds organs together

Loose connective tissue

More ground substance, cells, less fibers

Dense connective tissue

More fibers, less ground substance and cells

Regular dense

Fibers are parralel

Tendons connect muscle to bone

Ligaments connect bone to bone

Irregular dense

Fibers in various directions

Layers that support and surround organs and muscles fascia and dermis

Supportive connective tissue

Cartilage, blood, bone

Cartilage

gel type ground substance, shock absorption and protection, tolerates distortion

Cartilage where

Nose ears ends of long bones ribs knee

Bone

Matrix strengthened by calcium salts

Osteon- circular structural unit in bone

Blood

Watery matrix of dissolved proteins
