Anatomy and physiology Tissue Chapter

  1. 1. Tissues
  2. 2. And thistype.....
  3. 3. Epithelial TissueGeneral Characteristics:- Found throughout the body, covers allbody surfaces both inside and out.- Main glandular tissue.- Attached to underlying connective tissueby noncellular nonliving basementmembrane.- Usually has no vascular tissue - bloodsupply- Cells reproduce rapidly (rapid healing).
  4. 4. It takes about 27days for theouter layer ofskin to shed andbe replaced;that works out to1.5 pounds ofskin cells peryear.Wheredoes allthe deadskin youshed go?
  5. 5. Epithelial tissue is named basedon its descriptionsimple = single layerstratified = multiple layerssquamous = flatcuboidal = squarecolumnar = column (rectangle)
  6. 6. Simple SquamousFunction: diffusion and filtration. Air sacs in lungs, walls of capillaries
  7. 7. Simple Cuboidal Function: Secretion and Absorption Found in kidneys tubules, ducts and covering the ovaries
  8. 8. Stratified cuboidal epithelium
  9. 9. Simple Columnar Function: Secretion and Absorption Found in Digestive tract and uterus *Contains goblet cells to secrete mucus *Can have
  10. 10. Stratified Squamous Multi layer squamous, functions in protection Found in skin and mouth
  11. 11. The ink of tattoos must be injectedbelow the basement membrane.
  12. 12. Tissues often come inlayers on the body -superficial cuts on theskin may need to bestitched if they also gothrough the underlyingtissue.This will definitely needstitches!
  13. 13. Pseudostratified Columnar Single layer, nuclei are uneven which gives it a layered appearance Can have goblet cells and cilia Location: lining air passages and tubes of the reproductive system
  14. 14. Transitional Epithelium Stretchable Blocks diffusion (no leaking) Found in the urinary bladder
  15. 15. Glandular EpitheliumCells are specialized toproduce and secrete substancesThey make up the GLANDS exocrine glands | endocrine glands salivary, sweat hormones
  16. 16. Identify the tissues
  17. 17. Connective TissueGeneral Characteristics:-Most abundant tissue in your body, foundthroughout-Binds structures together-Provides support, protection, framework, fillsspace, stores fat, produces blood cells, fightsinfection, and helps repair tissue.-Composed of more scattered cells with abundantintercellular material matrix-Made up of a ground substance (fluid, semi-solid)and fibers-Most has a good blood supply
  18. 18. Types of Cells in Connective Tissue ● Mast cells (prevents clots) ● Macrophages (consumers) ● Fibroblasts (produce fibers) Collagenous (bones, ligaments, tendons) Elastic (respiratory)
  19. 19. Main types of FibersCollagenous fibers - strongand flexible bones, tendons andligamentsElastic fibers - very flexible,ears and vocal cords
  20. 20. Categories of Connective Tissue
  21. 21. Loose Connective Tissue or Areolar Tissue Binds underlying organs to skin and to each other Forms delicate thin membranes throughout the body
  22. 22. Adipose Tissue (fat)
  23. 23. Fibrous Connective Tissue Tendons = muscles to bones Ligaments = bones to bones
  24. 24. DENSE CONNECTIVE TISSUECARTILAGECartilage cells are calledchondrocytesProvides support and attachments,also cushions bones
  25. 25. Hyaline CartilageCovers ends of joints, nose and respiratorypassages
  26. 26. Elastic cartilage External Ear and Larynx
  27. 27. Hyaline cartilage
  28. 28. Hyaline cartilage
  29. 29. Fibrocartilage Tough, shock absorbing
  30. 30. Bone Tissue (Osseus)
  31. 31. Blood Tissue
  32. 32. Muscle Tissue
  33. 33. Cardiac muscle
  34. 34. Skeletal muscle
  35. 35. Smooth muscle
  36. 36. Nerve Tissue
  37. 37. Nervous tissue (spinal cord)
