connective tissue

  1. 1. Epithelial Tissue Connective Tissue Mascular TissueNervousTissue
  2. 2. kind of Biologicalacharacterized of theComposed by tissue that cells andabundancespecialized supports, of connects,extracellularextracellular or proteincomponents. different separatesfibers called matrix. types of tissues and organs of the body.
  3. 3.  categories ofconnective tissue basedon composition ofmatrix
  4. 4. primarycell type secreteextracellular proteins(fibers
  5. 5. Fibers:• collagen- long,straight, unbranched• reticular- thinner,flexible, branching• elastic- branchedand wavy
  6. 6. •Loose connective tissue is the mostcommon type of connective tissuein vertebrates. Functions: It holds organs in place and attaches epithelial tissue to other underlying tissues. It also surrounds the blood vessels and nerves.
  7. 7. Areolar Connective tissue-tissue that consists of a meshwork ofcollagen, elastic tissue, and reticular fibres- with many connective tissue cells inbetween the meshwork of fibres. Collagen fiber Elastic fibers Fibroblasts
  8. 8. Areolar Connective tissueFunctions: •Support •Strength, and •Elasticity.Location: •Areolar tissue is found in many locations around the body. •One important area is the skin
  9. 9. Adipose Connective tissue -a loose fibrous connective tissue packed with many cells (called "adipocytes") that are specialized for storage "fats". fat-filled vacuole
  10. 10. Adipose Connective tissueLocation: Functions: •Adipose tissue acts asaan insulating •Adipose tissue forms thick layer,under the skin, around layer •It also has a protective function, the kidneys and in the buttocks and support around some of the major organs. •A means of energy storage.
  11. 11. Dense Connective tissue- also called dense fibrous tissue,has fibers as its main matrixelement.
  12. 12. Dense regular Connective tissue -Provides connection between different tissues. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion .Includes: -tendons tough band of fibrous connective tissue th usually connects muscle to bone and is capable of withstanding tension -Ligaments the fibrous tissue that connects bones to other bones
  13. 13. Tendons Ligaments
  14. 14. Dense irregular Connective tissue-has fibers that are not arranged inparallel bundles Collagen irregularly arranged
  15. 15. Located:-This type of tissue is also in theprotective white layer of the eyeballand in the deeper skin layers.
  16. 16. •Blood• Lymph
  17. 17. Blood- plasma (watery matrix)formed elements:• Red blood cells (erythrocytes)• White blood cells (leukocytes)• Platelets2. LYMPHformed from interstitial fluidlymph vessels, lymph nodeslymphocytes (types of WBC) –immunity
  18. 18. erythrocytes Blood Vessel
  19. 19. Structural tissues – support andprotectionSolid matrix, lots of fibers w/ few cellrelative to matrixTwo main types1. CARTILAGE2. BONE
  20. 20. CARTILAGE CHONDROCYTES, found in Lacunae Matrix: solid/semi-solid (gelatinous) Ground: chondroitin sulfates Fibers: collagen, elastic, reticular Cartilage is avascular
  21. 21. 3 types of cartilage:1. Hyaline cartilage2. Fibrocartilage3. Elastic cartilage
  22. 22. BONECells: OSTEOCYTESGround: calcium salts,little fluidFibers: collagenBone has a well-developed blood supply
