connective tissue

Connective Tissue

Widely spaced cells, seperated by fibers and ground substance

function of connective tissue

-connects organs
-gives support and protection(physical and immune)
Stores energy and produces heat.
-Movement and transport of materials

Ground Substance

Space between the cells.
resists compression

ground substance is made of...

interstitual fluid, cell adhesion protein,proteoglycans

Fibers look like

red fibers running throught ground substance

fibers resist

Bending

fibers and ground substance make for...

a very strong tissue

Collogen fibers

White Fibers
Resist stretching, but flexible

Collogen fibers found in:

Tendons, ligaments and deep layers of skin

tendons

attach muscle to done

Ligaments

Attach bone to bone

Elastic Fibers

Yellow Fibers
Thin branching fibers of elastin proteins
stretch and recoil like rubberband

Elastic Fibers found in:

Skin, Lungs, and Arteries

All Fibers are:
Intracellular , Extracellular

Extracellular\No cells

Reticular Fibers

Thin cologen fibers coated with glycoproteins
Framework in spleen, lymph nodes, and basement membranes
