Connective tissue proper • Three types of fiber • Collagen fibers • Reticular fibers • Elastic fibers Connective tissue proper • Classified as loose or dense • Loose • Embryonic mesenchyme, mucous connective tissues • Areolar tissue • Adipose tissue • Reticular tissue • Dense • Dense regular CT • Dense irregular CT Fluid connective tissues • Distinctive collections of cells in a fluid matrix • Blood • Formed elements and plasma • Red blood cells, white blood cells and platelets • Arteries carry blood away, veins carry to the heart • Capillaries allow diffusion into the interstitial fluid • Lymph • Interstitial fluid entering the lymphatic vessels Supporting connective tissues • Cartilage and bone support the rest of the body • Cartilage • Grows via interstitial and appositional growth • Matrix is a firm gel containing chondroitin sulfate • Cells called chondrocytes
