Connective tissue proper (loose, dense, reticular, adipose) Loose connective tissue ○ ○ ○ More ECM than protein (watery and easy to break down) Contains blood vessels and immune cells Deep to the epidermis, in membranes lining hollow cavities and hollow organs Dense irregular connective tissue ○ ○ ○ ○ ○ Collagen is the main fibre (strong) More protein than ground substance Haphazard arrangement (lacking any organisation) Resists tension and forces from multiple directions (planes) Located in the dermis of the skin and connective tissue (capsules) around joints Dense regular connective tissue ○ ○ ○ ○ ○ ○ Collagen is the main fibre (strong) More protein than ground substance Parallel arrangement Resists tension and forces in one direction (plane) Located in the tendons and ligaments Different direction of force (different plane than the one its in), you can break the connective tissue e.g. rolling an ankle Elastic connective tissue ○ ○ ○ ○ ○ ○ Wavy appearance Dense because it has more protein Regular because it has a parallel arrangement Elastin is the predominant fibre Able to stretch and recoil Located in the elastic arteries (aorta) ■ High pressure of blood being forced into it form the heart ■ Recoil allows it to push blood around the rest of the body ○ Looks like an aero chocolate bar (because you can see the membranes) Yellow and oily in appearance Fat storing adipocytes White fat (main type in adults) provides fuel, insulation and shock absorption ■ SA because it lines the abdominal cavity which doesn’t have much bony protection so that the pressure doesn’t go to the internal organs Brown fat is mainly in children and adolescents for energy Adipose tissue ○ ○ ○ ○
