1. tissues group of structurally and functionally related cells and their external
environment that perform a common function
2. types of tissue epithelial, connective, muscle, nervous
3. extra cellular composed of substances surrounding the cells in a tissue
ma- trix (ECM)
4. functions of ECM provide strength, directing and holding cells, regulate: development,
mitotic activ- ity, and survival
5. ground contains interstitial fluid (H2O, nutrients, solutes, and compound
sub- molecules)
stance
6. glycosaminogl straight polysaccharide chains, referred to as chondroitin sulfate, negative
y- cans charges attract positively charged ions that draw water out of cells and
(GAGs) blood vessels
7. proteoglycans GAGs bound to protein core, manybind together to form aggregates
such as
hyaluronic acid, makes tissues more solid and resistant to compression
8. glycoproteins also known as cell adhesion molecules that glue cells together and
maintains
architecture of tissue
9. protein fibers provides tensile strength to ECM and includes collagen, elastic and
reticular fibers
10. collagen fibers very strong, resistant to tension and pressure, make up 20-25% of
proteins in the body
11. elastic fibers can stretch without breaking, able to return to original shape
