Cards in this deck (41)

  1. 14 types of TissuesEpithelial
    Connective
    Muscle
    Nervous
  2. 2Epithelial TissueIt is a covering and a lining
  3. 3Nervous TissueBrain and Spinal Cord
  4. 4Muscle Tissue3 types - smooth, cardiac, and skeletal
  5. 5Connective TissueMost abundant tissue by weight. It is everywhere. It is vascular
    Eg: blood.
  6. 6Number of cell layers in the 4 types of tissue layers1) Simple -1 row
    2) Stratified - more than 1 row
    3) Pseudostratified - False rows. Not actually stacked. Usu. columnar cells
    4) Transitional - Cells changing shape.
  7. 7Cell ShapesSquamous
    Cuboidal
    Columnar
  8. 8SquamousTend to be flat
  9. 9CuboidalLook like cubes. Very round nucleus with cytoplasm on all 4 sides. Located where there is absorption or secretion
  10. 10ColumnarNucleus usually in bottom 1/3 with cytoplasm on top. Simple columnar in digestive system
  11. 11Transitional Epithelial CellsIn bladder and urethra and ureters
  12. 12Simple Squamous EpitheliumAbove basement membrane (more superficial). Use nucleus placement for identification*** (Nucleus in 1 row)
  13. 13Simple Columnar EpitheliumGoblet cells. Most likely trachea or intestinal/digestive tract
  14. 14Stratified squamous epitheliumMultiple nuclei rows. Esophagus. Non-karatinized (no need for waterproofing)
  15. 15Stratified cuboidal epitheliumSalivary gland - equal cytoplasm, nuclei in centres of cells
  16. 16Transitional EpitheliumIn organs that change shape. eg. bladder
  17. 17Epithelial Tissue Surface Specialization1) Smooth Surfaces
    2) Microvilli
    3) Cilia
    4) Keratin
  18. 18Epithelial Tissue Surface Specialization - Smooth SurfacesEg. linings of blood vessels
  19. 19Epithelial Tissue Specialization - MicrovilliMultiple finger - like projections
    Increases surface area of cell/plasma membrane
    Absorption, secretion (eg. intestinal or urinary tract)
  20. 20Epithelial Tissue Surface Specialization - CiliaMultiple hair-like projections
    Transport material along cell/tissue surface (eg. trachea and mucus)
  21. 21Epithelial Tissue Surface Specialization - KeratinProtective waterproof substance in mature epithelial cells
  22. 22Pseudostratified columnar with ciliaEg lungs or trachea
  23. 23Keratinized stratified squamousHigh area of friction. Could be skin or esophagus, but we have a cornified (keratin) layer, which won't be present in esophagus
  24. 24Connective Tissue Classification - 2 typesProper and Specialized
  25. 25Connective Tissue Classification - Proper Typea) Loose
    -Areolar
    -Adipose
    -Reticular
    b) Dense
    -Regular
    -Irregular
    -Elastic
  26. 26Connective Tissue Classification - Specialized Typea) Bone
    -Spongy
    -Compact
    b) Blood
    c) Cartilage
    -Hyaline
    -Elastic
    -Fibrocartilage
  27. 27Loose Connective Tissue - AdiposeFat. Looks like big fat ping pong balls
  28. 28Loose connective tissue - AreolarMost abundant. Very loose. There are so many adipose cells in the body. Overweight people have larger adipose cells, and when they lose weight the cells shrink, but never disappear.
  29. 29Loose reticular connective tissueFramework of organs
  30. 30Dense regular connective tissueAchilles tendon (for an example)
  31. 31Dense Irregular Connective TissueSome branching, not perfectly straight and linear. Provides more give. Eg. heart pumping
  32. 32Elastic Connective TissueNeed them to open and close quickly. Eg. in arteries
  33. 33Spongy BoneArea where blood is produced
  34. 34Cartilage: HyalineBluish tinge on view (microscope) Eg. trachea. Has some give
  35. 35Cartilage: ElasticAreas where we need recoil. Eg. outer ear
  36. 36Cartilage: FibrocartilageIn areas of compression. Eg. b/w vertebrae
  37. 37Muscle TissueSmooth - no control over (eg. stomach. Involuntary)
    Cardiac - Heart muscle
    Skeletal - Voluntary. Biceps and triceps
  38. 38Cardiac MuscleIntercalated discs are the only way to tell the difference between cardiac and other types. 1 nucleus/cell. On slides note dark pink lines - intercalated discs
  39. 39Skeletal MuscleNuclei in periphery of cell. Can be binuceated. Lots of striations. Super long cells.
  40. 40Smooth MuscleNo striations, short and branching cells. Lining hollow organs (eg. bladder)
  41. 41Nervous TissueNo connective tissue within the brain and spinal cord. Space occupied by glial cells. Neurons have larger cell body and nuclei +/- axons
