Connective Tissues

Page 81 - 85

functions
Functions
  • Protection
  • Support
  • Binding together other body tissues
characteristics
Characteristics
  • Most connective tissues are vascularized (have good blood supply)
    • Ligaments and tendons are exceptions
  • Contains extracellular matrix
    • nonliving substance found outside the cells
    • produced by the connective tissue
types of connective tissue
Types of Connective Tissue
  • Bone = Osseous
  • Cartilage
  • Dense connective
  • Loose connective
    • Areolar
    • Adipose
    • Reticular
  • Blood
bone osseous
Bone / Osseous
  • Cells are in cavities (lacunae)
  • Matrix – hard; contains calcium salts and collagen fibers
  • Protects and supports
cartilage
Cartilage
  • Matrix is more flexible made of collagen fiber hidden by a rubbery matrix with a glassy white appearance.
  • Found in the larynx; covers ends of bones; attaches ribs to breastbone; skeleton of fetus
dense connective
Dense Connective
  • Main matrix are collagen fibers. More stretchy than cartilage matrix.
  • Makes of tendons and ligaments.
loose connective areolar tissue
Loose Connective – Areolar Tissue
  • Most widely distributed
  • Cushions organs
  • Has fluid matrix – appears to be empty space
  • “cobwebby” tissue
loose connective adipose tissue
Loose Connective – Adipose Tissue
  • Fat tissue
  • Matrix – droblet of oil in cell
  • Cushions organs such as kidneys and eyes; found under the skin
loose connective reticular tissue
Loose Connective – Reticular Tissue
  • Matrix – delicate network of interwoven reticular fibers
  • Support free blood cells in lymph nodes, spleen and bone marrow
blood
Blood
  • Vascular tissue
  • Matrix – blood plasma
  • Transports wastes, respiratory gases, nutrients and other substances.
