  1. Lab 2 Connective tissue (I) Jun Zhou(周俊）, Ph.D & M.D School of Medicine,Zhejiang University 20121008

  2. Connective tissue （part 1) 1.Spread slide (No. 4) (Drawing) 2.Loose CT (No.1) (small intestine) 3.Dense CT ( No.14) (finger skin) 4.Adipose tissue (No.14/No.6) 5.Reticular tissue (No.6) (lymph node)

  3. Classification • Connective tissue proper: Loose connective tissue Dense connective tissue Adipose tissue Reticular tissue • Specialized connective tissue: Cartilage Bone Blood

  4. Characteristics • Fewer cells ,more matrix, more cell types • No polarization • Numerous blood vessles • From mesoderm-mesenchyme

  5. Loose connective tissue macrophage fibroblast No.4 Spread slide H&E × 400 Collagenous fiber, Elastic fiber, Fibroblast, Macrophage

  6. Loose connective tissue Elastic fiber macrophage Collagenous fiber

  7. Loose connective tissue submucosa No.1 Small intestine: H&E × 40

  8. Fibroblast • Collagenous fiber Submucosa of small intestine: H&E × 400
