Intro chap 2 Flashcards
tightly packed sheet of cells with no visible ECM.
Cover in line, body surfaces, and cavities
Epithelia tissue
Connect tissue to one another
Bind support, protect transportation of substance
ECM is prominent feature for most
Connective tissue CT
Contraction (movement )
Muscle tissue
Consist of cell:
Nuro capable of generating sending receiving messages
*neuroglia support this activity
Nervous tissue
what does the extracellular matrix do ?
composed of substances(made of different parts) and a liquid gel or solid that surrounds cells
provide tissue with strength
Direct cells to proper position
*** hold cells in place and helped them function properly and tissue and organs.
what are the two main components of the extracellular matrix
Ground substances & protein fibers
make up most of ECM (extracellular matrix)
And what is it components of?
ground substances
composed of :
water, nutrient, ions and macromolecules
what is chondroitin sulfates
found in Cartlidge and helped the join stay flexible
hyaluronic acid
hope the skin stay moist basically hydrated
cell adhesion molecules (CAMS)
made up of different type of glycolprotein
Big molecules
work together to support structure
glycosaminoglycans
chondroitin sulfate & hyaluronic acid
Proteoglycans
gags bound to a protein core (bottle brush )
They help give tissues like cartilage their strength and flexibility. GAGs are really good at attracting water, which makes them great for cushioning and protecting areas like joints.
They are hydrophilic ( likes water)
Protein fibers
collage fibers
elastic fibers
reticular fiber
collagen fibers
WHITE
20-25 of all protein body
resistant to tension
( they are strong , help body resist pulling )
Elastic fibers
protein elastin, surrounded by glycolprotein
Exhibit elasticity (Bounce back )
Yellow
