MICRO 20 Lecture Notes - Lecture 5: Central Canal, Red Blood Cell
Document Summary
Collagen fibers thick bundles that resist pulling forces from their. Thin fibers with ability to stretch and return to normal shape. Reticular fibers short and branched that produce frame in tissue called stroma and thicker than elastic fibers. White ground substance with lots of collagen and elastic fibers. Adipose tissue fat cells called adipocytes in adipose tissue or skin cells. Dominated by fibers with very little ground substance and some fibroblasts nuclei. Tons of pink/purple collagen fibers arranged parallel to one another that resist pulling forces when pulled from ends. Tons of pink/purple collagen fibers arranged in all directions that resist pulling from all ends. Smooth pink to purple matrix with non visible collagen fibers with cartilage cells called chondrocytes in lacunae. Strong, rigid, support tissue to serve as cushion. Black/dark elastic fibers in in matrix with very large chondrocytes in lacunae. Tons of collagen fibers that stain teal with very small chondrocytes in lacunae (red nuclei)
