What are the 4 major classifications of connective tissue?
connective tissue proper
bone
blood

All connective tissue arises from?
embryonic (mesenchyme) tissue
Connective tissue ranges from ____ to _____?
avascular to vascular
Cells are suspended and separated in?
extracellular matrix
Why do matrix support cells?
bear weight
withstand tension
endure abuse
What substance fills the space between the cells?
ground substance
What is ground substance made up of?
interstitial fluid
cell adhesion proteins
proteoglycans
water
fibers of the connective tissue provide what?
support
These fibers are extremely strong and provide high tensile strength to the connective tissue.
collagen fibers
These fibers contain elastin, which allows them to be stretched and recoil.
elastic fibers
These fibers are fine, collagenous fibers that form networks where connective tissue contacts other types of tissues.
reticular fibers
Suffix for immature
-blast
Suffix for mature
-cyte
Immature (blast) cells are actively _____?
mitotic
Immature (blast) cells secrete the fibers and ground substance typical of?
a specific tissue
Fibroblasts are found where?
connective tissue proper
Chondroblasts are found where?
cartilage
Osteoblasts are found where?
bone
These cells are less active, and maintain the health of the tissue
mature (cyte) cells
What is the job of a fat cell?
to store nutrients
What is the job of white blood cells?
tissues response to injury
What is the job of mast cells?
initiate a local inflammatory response against foreign microorganisms they detect
What are macrophages?
phagocytic cells that “eat” dead cells, and microorganisms; function in the immune system
