2. General Characteristics  Connective tissue is the most abundant tissue in your body.  They provide protection, support, framework, fills space, stores fat, produces blood cells, fights infection, and helps repair tissue.  They are composed of more scattered cells with abundant intercellular material matrix.  Most connective tissue have a good blood supply  Connective tissue is made up of a ground substance (fluid, and semi-solid) and fibers

3. Common Types of Cells  Mast cells (prevents blood clots)  Fibroblasts (most abundant, produces fibers)  Macrophages (Phagocytic)

4. Main types of Fibers  Collagenous Fibers – are thick, made of protein collagen, major structural protein in the body, strong, flexible, not very elastic, appear in long parallel bundles, is known as white fibers.  Elastic Fibers – not as strong, but very elastic (respiratory and vocal cords)

5. Elastic Fibers and collagenous fibers

6. Categories of Connective  Loose C.T.  Adipose Tissue (Fat)  Dense C.T. (Fibrous Tissue)  Cartilage -Hyaline -Elastic -Fibrocartilage  Bone tissue  Blood Tissue  Reticular

7. Loose Connective Tissue  The Loose Connective Tissue binds skin to underlying organs and organs to organs. It also fills in spaces between muscles throughout the body.

8. Dense Connective Tissue  Fibrous Tissue  Closely packed.  It also has thick, collagenous fibers and fine network of elastic fibers.  Includes tendons and ligaments.

9. Cartilage  All cartilage cells are called Chondrocytes. o Hyaline- covers end of bones and joints. o Elastic- external ear and larynx o Fibrocartilage- Invertebral disks Hyaline Cartilage-smooth with large nuclei.

10. Bone Tissue  Bone tissue is the osseus tissue.  Rigid due to mineral salt  The layers in bone tissue are haversian canals, mellae, osteocytes.

11. Blood and Reticular  The Blood tissue circulates throughout the body  The Reticular tissue is scattered throughout the body Blood- identify due to platelets.
