Connective Tissue • Features • Cells far apart with matrix between • Matrix • Protein fibers • Ground substance • Not usually on body surface • Can be hard to liquid • Bone and blood are connective
Vascular – except cartilage and tendons • High nerve supply- except cartilage
Connective Tissue Cells • Fibroblasts • Secrete the fibers and matrix of tissue • Mast Cells • Along blood vessels • Secrete histamine • Macrophages • Do phagocytosis, are white blood cells
Plasma cells – another white blood cell • Adipocytes • Fat storage cells
Extra cellular Matrix • Ground Substance • Contains different substances depending on tissue type • Can be watery or cement like • Hyaluronic acid is viscous and slippery for joints
Fibers • Collagen Fibers • Largest • Strong • Flexible • Collagen protein • Bone, cartilage, tendons, ligaments
Elastic fibers • Smaller than collagen • Promotes ability to stretch • Marfan’s • Reticular fibers • Smallest • Give support and strength • Stroma (framework) of some organs
Connective tissue types • Major types • Embryonic • mesenchyme • Loose connective • Areolar • Adipose • Reticular
Dense Connective • Dense regular • Dense irregular • Elastic connective • Cartilage • Hyaline • Fibrocartilage • Elastic cartilage
