  2. Connective Tissues: Structure • Support and barriers • Ground substance • Cells • Fixed • Mobile

  3. Connective Tissues: Structure • Fibers and their functions • Fibroblast cells • Collagen • Elastin • Fibrillin • Fibronectin

  4. Connective Tissues: Types

  5. Cells and Fibers of Loose Connective Tissue Figure 3-29 (1 of 2)

  6. Cells and Fibers of Loose Connective Tissue Figure 3-29 (2 of 2)

  7. Dense Connective Tissues • Strength or flexibility • Tendons and ligaments • Collagen dominates
