matrix (ground and fibers)

immature '-blast' cells often divide and secrete _____

bone and cartilage

immature '-blast' cells become mature '-cyte' cells in ____ and ____ CT

macrophages, plasma cells, mast cells, adipocytes, white blood cells (MAPWM)

there are 6 main types of cells in matrix of connective tissue: list them....

fibroblasts

_____ are usually the most numerous cells in CT.

fibroblasts

_______ are flat cells that excrete fibers and some of ground substance

collegen

fibroblasts produce _______

macrophage

a ______ is a kind of white blood cell that is a big irregular blobs that eats bacteria and debris and is found in CT matrix, but not the most common white blood cell

plasma

_____ cells make antibodies

mast

_____ cells are most abundant in CT that underlays epithelial tissue.

mast

_____ cells produce histamine and therefore is part of the bodies inflammatory response

histamine

_______ dialates blood vessels and restricts broncial making breathing more difficult

adipocytes

_______ are fat cells found in CT that store triglycerides

skin and organs

adipocytes are stored deep in ____ and _____

white blood

there are not many ____ cells found in CT and only when there is an infection.

neutrophils and eosinophils

There are two main types of white blood cells in CT:
_____ and _____

eosinophils

____ is a kind of white blood cell that is involved in allergic reactions where there is parasitic invasion

ground substance

_____ contains water, proteins and polysaccharides.

glycosaminoglycans or GAGs

the colleccive name for the polysaccharides in the ground substance of CT is ________

fibronectin

_______is the main adhesion protein in the CT matrix is mainly involved in gluing cells to matrix (but also trapping and linking)

polysaccharides

______ in the CT attract WATER

hyaluronic acid and chondroitin sulfate

2 important GAGs (polysaccharides) in CT are: ______ and _______

hyaluronic acid

the GAG _____ in CT is viscous, slippery and lubricates.

joints

hyaluronic acid is a GAG found in ____

Sperm and white blood cells

____ cells and _______ cells produce an enzyme to break down hyaluronic acid (hyaluronidase) to make it more watery so that they can move easier.

hyaluronidase, bacteria

unfortunately ________ (the enzyme produced by white blood cells for easier migration) in connective tissue helps ______ spread quickly.

chondroitin sulfate

______is a GAG found in cartilage bone and skin and blood vessels

kermatan, keratan

____ sulfate and ______sulfate are minor GAGs found in CT.

chondroblasts

______ are cartilage CT cells

osteoblasts

________ are in bone CT cells

are White blood cells (apart from macrophages) that are phagocytes

collagen, elastic, reticular

There are 3 main fibers found in CT: ____, ____, ____

collagen, elastic, reticular

___ and ___ fibers in CT are made of PROTEIN while _____ fiber is made of protein (elastin) wrapped in glycoprotein (fibrillin)

elastin

_____ is strong but the most flexible fiber in CT and is found in the lungs and blood vessel

collegen

______ fibers found in CT are parallel bundles, are strong and somewhat flexible.

collagen

______ fibers are found in bone, cartilage, tendons, ligaments and areolar CT

reticular

_____ fibers are the most tough fiber

reticular

_____fiber is found in loose CT of basement membranes, the spleen and lymph nodes.

reticular

___ fibers form a framework of thin fibers in areolar and adipose (both loose CT) and smooth muscle tissue.

hyaluronic acid

the GAG found in joints is ______

reticular

GAGs are found in the ________ of _______

...

____ are polysaccharides in ground substance
