Cards in this deck (34)

  1. 1DENSE CONNECTIVE TISSUEIts a connective tissue proper. Contains more collagen fibers than does loose connective tissue so it is a greater resistance to stretching.
    - regular
    - irregular
  2. 2DENSEREGULAR CONNECTIVE TISSUEIt is a dense connective tissue proper. The fibers are parallel to each other.
    Flexibility in one direction
    ligaments (not all fibers are parallel) and tendons.
  3. 3DENSE IRREGULAR CONNECTIVE TISSUEIt is a dense connective tissue proper. The fibers are random distributed.
    Flexibility in all directions
    The dermis of the skin, arterial walls
  4. 4LOOSE CONNECTIVE TISSUEIt is a connective tissue proper.
    The fibers leaves large spaces between them.
    - Areolar
    - Adipose
    - Reticular
  5. 5AREOLAR TISSUEIt is a loose connective tissue, a connective tissue proper.
    is distributed in a random, web-like fashion.
    It fills the spaces between muscle fibers
  6. 6RETICULAR TISSUEIt is a loose connective tissue, a connective tissue proper.
    Is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver
  7. 7ADIPOSE TISSUEIt is a loose connective tissue, a connective tissue proper.
    Consists mostly of fat storage cells, with little extracellular matrix.
    A large number of capillaries allow rapid storage and mobilization of lipid molecules
  8. 8WHITE ADIPOSE TISSUEIt is a loose connective tissue, a connective tissue proper.
    Is most abundant.
    Can be found protecting the kidneys and cushioning the back of the eye
  9. 9BROWN ADIPOSE TISSUEIt is a loose connective tissue, a connective tissue proper.
    Is more common in infants.
    Is found mainly in the neck and clavicular regions of the body
  10. 10SUPPORTIVE CONNECTIVE TISSUEProvide structure and strength to the body
    and protect soft tissues.
    - Cartilage (Hyaline, Elastic and fibrocartilage)
    - Bone
  11. 11BONEIt is a supportive connective tissue.
    The matrix is rigid and described as calcified because of the deposited calcium salts
  12. 12FLUID CONNECTIVE TISSUEVarious specialized cells circulate in a watery fluid containing salts, nutrients, and dissolved proteins.
    - Blood
    - Lymph
  13. 13FIBROBLASTThe most abundant cell in connective tissue proper.
    Secrets polysaccharides and proteins.
  14. 14FIBROCYTEA less active form of fibroblast, is the
    second most common cell type in connective tissue proper
  15. 15ADIPOCYTEcells that store lipids as droplets that fill most of the cytoplasm.
    - White
    - Brown
  16. 16WHITE ADIPOCYTESA single large drop and are metabolically less active.
  17. 17BROWN ADIPOCYTESA many droplets, and have high metabolic activity.
  18. 18MESENCHYMAL CELLA multipotent adult stem cell.
    These cells can differentiate into any type of connective tissue cells needed for repair and healing of damaged tissue
  19. 19MACROPHAGE CELLA large cell derived from a monocyte, a type of blood cell, which enters the connective tissue matrix from the blood vessels.
    An essential component of the immune system, which is the body’s defense against potential pathogens and degraded host cells
  20. 20COLLAGEN FIBERSecreted by fibroblast.
    Is made from fibrous protein subunits linked together to form a long and straight fiber. Collagen fibers, while
    flexible, have great tensile strength, resist stretching
  21. 21ELASTIC FIBERSecreted by fibroblast.
    Contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that after being stretched or compressed
  22. 22RETICULAR FIBERSecreted by fibroblast.
    Is made from fibrous protein subunits.
    They are found throughout the body, but are most abundant in the
    reticular tissue of soft organs, such as liver and spleen
  23. 23THE DISTINCTIVE APPEARANCE OF CARTILAGEIs due to polysaccharides called chondroitin sulfates, which bind with ground substance proteins to form proteoglycans
  24. 24CHONDROCYTESCartilage cells
  25. 25LACUNAEThe space the chondrocytes occupy
  26. 26PERICHONDRIUMA layer of dense irregular connective tissue that encapsulates the cartilage
  27. 27HYALINE CARTILAGEThe most common type of cartilage.
    Consists of short and dispersed collagen fibers and contains large amounts of proteoglycans.
    It is found in the rib cage and nose and covers bones where they meet to form moveable joints.
  28. 28FIBROCARTILAGEIt is a type of cartilage.
    Is tough because it has thick bundles of collagen fibers dispersed through its matrix.
    Menisci in the knee joint and the
    intervertebral discs
  29. 29ELASTIC CARTILAGEIt is a type of cartilage.
    contains elastic fibers as well as collagen and proteoglycans.
    This tissue gives rigid support as well as elasticity.
    The external ear contains elastic cartilage.
  30. 30OSTEOCYTESBone cells.
    Are located within lacunae
  31. 31HEMATOPOIETIC STEM CELLSDerives the formed elements circulating in the blood.
    Located in bone marrow
  32. 32ERYTHROCYTESRed blood cells
    Transport oxygen and some carbon dioxide
  33. 33LEUKOCYTESWhite blood cells
    Responsable for defending.
  34. 34PLATELETSCell fragments involved in blood clotting
