  1. Functions of connective tissue
    • • Maintenance of structural integrity
    • • Mechanical support
    • • Protection > residence of immune cells
    • • Metabolite exchange
    • • Homeostasis
    • • Energy storage
    • • Repair
  2. What makes up connective tissue?
    • Cellular components
    • Extracellular matrix
    • > Fibrous components
    • > Ground Substance (Proteins)
  3. Three classes of CT
    • Enbryonic
    • Specialized (bond, blood)
    • CT Proper 
  4. Embryonic CT
    • 1. Mesenchyme
    • > Many Mesenchyme cells > can turn into any CT
    • > Little collagen
    • 2. Mucous CT
    • > Wharton's jelly
    • > Found in umbilical cord
  5. Types of CT 
    • Collagenous CT
    • >Loose
    • >Dense
    • >>Irregular
    • >>regular
    • Specialized CT
    • >Reticular, Elastic, Adipose, Cartalidge, Bone, Blood
  6. Loose CT
    • A lot of cells, Little (Fine) collagen
    • Beneath covering Epithelia
    • Diffusion
    • Site of immune response
  7. Dense CT
    • Few and single type cells fibroblasts
    • Lots of collagen > Type 1
    • Little ground substance
    • Functions for strength
    • Dermis and submucosa (GI)
  8. Dense Regular CT
    • oarallel collagen bundles
    • Tendons
    • Ligaments
    • Aponeurosis > flat tendons
    • Cornea > transparency
  9. Reticular CT
    • Specialized
    • Type III collagen
    • Bone marrow, Lymph nodes, and spleen
    • Sponge structure > small delicate fibers
    • Periodic acid shiff > silver stain
  10. Elastic Fibers
    • Specialized CT
    • Aorta and Ligament flavum (very few places)
    • Large elastic fibers
  11. Adipose CT
    • Does not stain well
    • Specialized CT
    • Nucleous usually pushed to the side
  12. CT cellular components
    • Indigenous cells
    • Immigrant cells
    • Transient cells
  13. CT Fibrous components
    • Collagen
    • Elastic Fibers
    • Reticular Fibers
  14. Ground Substance
    • Proteoglycans - Glycosaminoglycans
    • Glycoprotiens
    • Tissue Fluids
  15. Fibroblasts
    • Synthesis of EM
    • round elongated nucleous
  16. White Adipocytes
    • Synthesis and storage of triglycerides
    • Single droplet > pushes everything to the periphery 
  17. Brown Adipocytes
    • Heat Production
    • Multiple drooplets
    • Smaller
    • Many Mito
    • Abundant in newborn
  18. Mast Cells
    • Permeanent Ubiquitius in CT
    • Found in areas where immunity is needed
    • Receptors for IgE at the surface of mast cells 
    • Secreation of mediators
    • Oval small, found in clusters, granules
    • Metachromasia > change the color of the dye
  19. Macrophages
    • Ganitor > Phagocytosis
    • Large, Irregular outline, KIDNEY-shaped nucleous
    • labeled with trypan blue, india ink, immunological markers
  20. Plasma Cells
    • synthesis and secreation of Ig-s and AntiBodies
    • round, small, Eccentric nucleus > clockface
  21. Collagen classification
    • 1. Fibril-forming collagen
    • > 1,2,3,5,11
    • 2. Fibril-Associated collagen
    • > 9,12,14
    • 3. Network Forming collagen
    • > 4,7,6
    • 4. Cell Associated Collagen
    • > 17
    • 28 different types
  22. Fibrillogenesis
    • The process of making collagen
    • 1. Intracellular
    • >Preprocollagen are made in RER
    • >Cleaved, Hydroxylated (Vitamin C required), Glycosylation, Formation of Procollagen (triple helix of 3 alpha chains)
    • 2. Extracellular
    • > Collagen molecule is formed by the cleaage of the uncoiled propeptieds
    • > Collagen fibrils formed by agregated collagen molecules
    • > Associate longitudinally and laterally to form collagen fibers 
  23. 1D period
    • Collagen comes together in a striated manner
    • 1D period = 67nm
  24. Type II collagen
    Does not form fibers or bundles (cartilage)
  25. Elastic Fiber
    • Complex of 19 different protiens
    • Fibrillins, Tropoelastin...
    • Amorphous and microfibrillar components
    • outside is hydrophobic
    • crosslinked domain
  26. Ground Substance
