Lect. 10: Histology II (Connective tissue proper) Assoc. Prof. / Reda M. Mansour & Radwa Lutfy What is connective tissue Connective tissues connect, support and help bind other tissues in the body. It originates from mesoderm. Main functions of connective tissue 1. Provides structural support to tissues and organs. 2. Serves as medium for exchange of metabolic wastes, nutrients and oxygen between blood and body cells. 3. Site of fat storage (adipose tissue). 4. Aids in defense and protection of the body by their phagocytic and immunocompetent cells. Main components of connective tissue Connective tissue Matrix Cells Fibers (ground substance ) Fibers are : Collagen Elastin Reticular Semi-Solid Fluid Rubbery Solid C.T. Cartilage Blood Bone proper  Classification of connective tissue * Connective tissues are divided according to ground substance (matrix) into: 1- Connective tissue proper (with gelatinous or semi- solid ground substance) 2- Vascular or fluid connective tissue (with fluid or liquid ground substance) 3- Skeletal or supporting connective tissue (with solid or rubbery ground substance) Classification of connective tissue according to matrix or ground substances Semi-solid matrix Solid or rubbery matrix Liquid matrix Histology of Loose Connective Tissues. This is the “packing material” of the body, filling spaces between other structures. Histology of Loose Connective Tissues. Areolar connective tissue Histology of Dense Connective Tissues Histology of Dense Connective Tissues
