Connective Tissue

Messenchyme- embryonic connective tissue, gel like ground substance containging fibers, star shaped cells
function- give rise to all other connective tussue
loctation- in embryo

loose connective tissue-
aerolar- fibroblasts, macrophages, mast cells, some white blood cells
Function- wraps and cushions organs, plays important role in inflammation, holds and conveys tissue fluid
Location- under Epithelia of body, forms mucus membranes, packages organs, surrounds capillaries

adipose- fat cells, nucleus pushed to side but fat droplet
Function- reserve food fuel, insulates against heat loss, supports and protects organs
Location- under skin, around kidneys and eyeballs, within abdomen, in breasts

Reticular- network of reticular fibers in a typical loose ground substance
Function- form a soft internal skeleton that supports other types
Location- lymphoid organs- lymph nodes, bone marrow, spleen

Dense connective tissue
Dense regular- parallel collagen fibers, few elastin fibers
Function- attaches muscle to bone or other muscle, attaches bones to bones, withstands great stress coming from one direction
Location- tendons, most ligaments

Dense irregular- irregularly arranged collagen fibers, some elastic fibers
Function- able to withstand tension exerted from many directions, provides strength
Location- dermis of skin, submucosa of digestive tracts, fibrous capsules of organs and joints
