VII. Events in Tissue Repair • Two Methods: Regeneration and Fibrosis A. Regeneration = STEPS 1. Inflammation § Capillaries permeable and clotting proteins leak out § Blood clot forms trapping Bacteria § Scab forms 2. Granulation Tissue Forms § = pinkish immature connective tissue § New capillaries grow in 3. Surface Epithelium Regenerates § Regeneration of surface epithelium § Scab detaches Copyright © 2009 Pearson Education, Inc. , publishing as Benjamin Cummings
4. There May Be Some Scar Tissue Beneath 5. Tissues: epithelial, connective except cartilage B. Fibrosis = 1. Depends on: 2. Scar Tissue Repair by dense connective tissue 3. Tissues With No or Poor Regeneration § Cardiac muscle: none § Nervous: some mitosis § Skeletal muscle: some mitosis Copyright © 2009 Pearson Education, Inc. , publishing as Benjamin Cummings
VIII. Health Concerns– Cancer (crab) - How Common: approx. ½ population develops; 1/5 die A. Carcinogens & Mutations • Oncogenes & Tumor Suppressor Genes B. Increased Cell Division– not controlled C. Tumor (Neoplasm) Develops • Benign OR Malignant D. Malignancy Develops • Metastisis: E.
