  2. Class Assignments What By When • Read 80-111 9/12/06 • Due this class period • Due next class period • Due in the future

  4. Glandular Epithelium • Secretion of a product • goblet cells • found in PSCC and columnar epithelium • secrete mucus • Glands • endocrine - inside the body • exocrine - outside the body

  5. Connective Tissue • Keeps other tissues in place • Protein fibers found in C.T. • 1. Collagen • thick - resists stretching (tensile strength) • Tendons and ligaments, scar tissue • 10% of human’s weight

  6. Connective Tissue • 2. Elastin • Elasticity and Extensibility • can stretch and return to original shape • skin • 3. Reticulin • very thin • not prominent

  7. Connective Tissue • Fig. 4-2 p. 91 • Many types of connective tissue

  8. Connective Tissue • Fibroblast - cell that produces intercellular matrix (proteins) • 1. Loose connective tissue (aka - areolar tissue) • random protein fibers - collagen and elastin mostly • found between skin & muscles and between organs

  9. Connective Tissue • 2. Adipose tissue • large spherical cells • protein present - reticulin • fat storage • 3. Dense regular connective tissue Proteins are organized (parallel) • tendons and ligaments

  10. Connective Tissue • 4. Dense irregular connective tissue • matting of protein (not parallel fibers) • Dermis - deep layer of skin • Wrapping around bones and cartilage • Periosteum or endosteum

  11. From: http://tray.dermatology.uiowa.edu/DPT/Hist/Nrml-001.htm

  12. Cartilage • Much harder than other types of connective tissue • protein fibers mixed with ground substance - matrix • chondrocytes - cartilage cells • found in lacunae
