Document Summary
Connective tissue aides with structural support, medium for exchange, storage of lipid, defense. Also known as connective tissue proper or specialized connective tissue. Consists of cells and large amount of ecm. Function to ensure that connective tissue is hydrated and gel-like. Three major types of connective tissue which are collagen fibers, reticular fibers, and elastic fibers. Collagen- they are striated in electron microscopy and the most abundant fiber in type i collagen. Reticular fibers: main properties are thin fibers of type iii collagen that are highly glycosylated. Main property is that the contain polymers of elastin protein and are found in tissues where stretch and recoil are required. There are many different ways to distinguish between difference types of connective tissue. Loose(areolar) connective tissue, dense irregular connective tissue, dense regular connective tissue, adipose tissue, and reticular tissue. Lots of cells and ground substance but contain few fibers. Prominent in the lamina propria underneath wet mucosal membranes.
