Presentation Transcript

  1. Warm up 10/21/2013Identify the following tissues:

  2. Histology Connective Tissue

  3. Connective Tissue • Most widespread in the body

  4. Functions: • Connects (tendons and ligaments • Supports (skeleton and cartilage

  5. Functions: • Transports (blood) • Defends (immune cells in tissue)

  6. Tissue Composition: • Intercellular material or matrix • Immune cells in matrix

  7. Matrix made of: • Cells • varies by tissue type • Fibers • 3 types • Fluid (ground substance or GS)

  8. 3 Fiber Types: • Collagen • means white • Protein - collagen • strongest fiber • mostly in bundles

  9. 3 Fiber Types: • Collagen • Most abundant protein in the body

  10. 3 Fiber Types: • Reticular • Protein - reticulin • delicate fiber

  11. Reticular Fibers

  12. 3 Fiber Types: • Elastic • Protein - elastin • stretchy fiber

  13. Elastic Fibers

  14. Elastic Fibers

  15. Loose Connective Tissue (CT):1. Areolar • Cells - fibroblasts, macrophages, mast cells • Fibers - Collagen, elastic, little reticular • GS – loosely arranged in jelly material

  16. Loose CT :1. Areolar • Fibroblasts – produce collagen

  17. Areolar (Loose Fibrous)

  18. Areolar Tissue • Yellow – Elastic • Blue – Macrophages • Green – Collagen • Red - Fibroblasts

  19. Loose CT :1. Areolar • Under skin (fascia) • Separates muscles • Around blood vessels

  20. Loose CT :2. Adipose • Cells – just add adipocytes (fat cells) • Fibers - Collagen, reticular • GS – closely-packed cells in jelly material

  21. Loose CT :2. Adipose • Functions: Insulate, protect and energy reserve

  22. Loose CT : Adipose

  23. Loose CT : Adipose

  24. Loose CT : Adipose

  25. Loose CT : 3. Reticular • Cells – Reticular • Fibers - Reticular • GS – loosely arranged in jelly material - trapped cells

  26. Loose CT : Reticular • 3-Dimensional web or net • Fx: Filtration • Spleen, Bone marrow, Lymph nodes

  27. Loose CT : Reticular • Fx: support • Liver and kidney

  28. Loose CT : Reticular

  29. Let’s practice!!! 3. 1. 2.

  30. Dense CT :1. Dense Regular • Densely-packed fibers in the matrix

  31. Dense CT :Dense Regular • Cells – fibroblasts • Fibers – Collagen • GS – Parallel arranged bundles of fibers - Few cells or GS

  32. Dense CT :Dense Regular • Provides strength • Tendons – connect muscle to bone

  33. Dense CT :Dense Regular

  34. Dense CT :Regular (tendons)

  35. Dense CT :2. Dense Irregular • Cells – fibroblasts • Fibers – Collagen • GS – Randomly arranged bundles of fibers w/ few cells

  36. Dense CT :Dense Irregular • Forms • dermis of skin • Outer kidney and spleen

  37. Dense CT :Dense Irregular • Fx • Connection • Support

  38. Dense CT :Dense Irregular Dermis of skin Outer kidney capsule

  39. Dense CT :3. Dense Elastic • Cells – fibroblasts • Fibers – Elastic • GS – Parallel arranged bundles of fibers w/ few cells and little GS

  40. Dense CT :Dense Elastic • Some flexibility • Forms • Ligaments – connect bone to bone • Blood vessel walls

  41. Dense CT :Elastic (ligament)

  42. Dense Fibrous :Elastic (vessel wall) 7

  43. Loose vs. Dense

  44. 10/22/2013 Warm up – Identify tissues 1. 2. 3. 4.

  45. Bone Tissue: • Functions • Support • Protection • Minerals

  46. Lacunae with Osteocyte Lacunae containing osteocyte

  47. Bone Tissue :1. Compact (dense) Bone • Cells – Osteocytes • Fibers – Some collagen • GS – Calcium deposits

  48. Compact Bone : Shaft of Long Bones Lacunae with osteocyte Haversian Canal Calcium salt GS

  49. Bone Tissue :2. Spongy (cancellous) Bone • Cells – Osteocytes • Fibers – Some collagen • GS –Calcium deposits

  50. Spongy (cancellous) Bone : End of Long Bones and Flat bones
