Presentation Transcript

  1. Connective Tissue

  2. Connective tissue • Made of cells suspended in an extra-cellular matrix • Three types of fibers • Collagen fibers • Strong fibers • Elastin fibers • Flexible fibers • Reticular fibers • Create a delicate framework

  3. Types of connective tissue

  4. Areolar (loose) Tissue • Few collagen fibers • Cells of this tissue are spread out in the matrix

  5. Lots of reticular fibers • May be hard to see on the slides

  6. Dense Connective Tissue • Abundant collagen fibers • Closely packed • Fine network of elastin fibers

  7. Elastic Connective Tissue • Mainly elastin fibers • Between collagen fibers and fibroblasts • May be hard to see on the slides

  8. Cartilage • Rigid connective tissue • Provides support • Matrix is abundant and made of… • Abundant collage fibers • Gel-like ground substance • Characteristic cells are found in little “pocket-like” structures called lacunae

  9. Hyaline Cartilage • Most common type of cartilage

  10. Elastic Cartilage • More flexible than hyaline • Has more elastin fibers

  11. Fibrocartilage • Very tough tissue • Abundant collagen fibers

  12. Bone (osseous tissue) • Most rigid tissue • Cells also found in lacunae

  13. central (Haversian) canal perforating (Volkmann) canal

  14. Blood • Cells are suspended in a fluid matrix • plasma • Characteristic cells=red blood cells (RBC’s) and white blood cells (WBC’)
