  1. Tissues Ch. 4: The Fabric of Life

  2. Tissue Types • Epithelial tissue • Covers • Connective tissue • Supports • Muscle tissue • Moves • Nervous tissue • Controls

  3. Tissue Types • Epithelial Tissue • Cover structures and organs • Lines cavities • 2 Types of epithelium • Covering and Lining epithelium • Glandular epithelium • Functions as an interface tissue • Protection • Absorption • Filtration • Excretion • Secretion • Snesory reception

  4. Tissue types • Special Epithelial Characteristics • Polarity • Specialized Contacts • Supported by Connective Tissue • Avascular but innervated • Regenerative Capacity

  5. Tissue Types • Classification of epithelia • Simple epithelia • Stratified epithelia • Epithelia Cell types • Squamos • Cuboidal • Columnar

  6. Simple Epithelia • Simple Squamous Epithelium • Endothelium • Mesothelium

  7. Simple epithelia • Simple Cuboidal Epithelium

  8. Simple epithelia • Simple Columnar Epithelium

  9. Simple epithelia • Pseudostratified columnar epithelium

  10. Stratified Epithelia • Stratified Squamous Epithelium

  11. Stratified Epithelia • Transitional Epithelium

  12. Glandular Epithelia • Endocrine glands • Produce hormones • Ductless

  13. Glandular Epithelia • Exocrine glands • Unicellular (mucous and Goblet cells)

  14. Glandular Epithelia • Exocrine glands (cont.) • Multicellular • Structural classifications • Fig 4.5

  15. Connective Tissue • Common Characteristics • Mesenchymal origin • Varying vascularity • Extracellular matrix

  16. Connective tissue • Structural Elements • Extracellular matrix • Fibers • Ground substance • Cells • Fat Cells • WBC’s (neutrophils, eosinophils, lymphocytes) • Mast Cells = mediate inflammation • Macrophages Fig 4.7

  17. Connective tissue • Fibers • Collagen Fibers • Elastic Fibers • Reticular fibers Fig 4.7

  18. Connective Tissue • Primary Cells by tissue type table 4.1 • Connective Tissue Proper • Fibroblasts • Cartilage • Chondroblasts/Chondrocytes • Bone Tissue • Osteoblasts/Osteocytes • Blood • Erythrocytes • Leukocytes • Platelets

  19. Connective tissue • Types of connective tissue • Connective Tissue Proper • Loose connective tissue: Areolar, Adipose, Reticular • Dense Connective Tissue: Regular, Irregular, Elastic • Cartilage • Hyaline • Elastic • Fibrocartilage • Bone • Blood

  20. Connective tissue: Proper • Loose Connective Tissue • Areolar
