1. Chapter 5 Tissues

2. cells- basic unit of structure and function tissues- cells that are organized into groups and layers carry out specific functions

3. 1. epithelial- forms protective coverings fxns to secrete and absorb covers body surfaces and organs 2. connective- supports and binds structures found thru-out body

4. 3. muscle- produces body movements or moves substances 4. nervous- conducts impulses that integrate/coordinate body activities

5. ALL tissues contain extracellular matrix non-living transmits signal from outside in influences how cells fxn

6. list characteristics of ET list 4 fxns describe how classified; include special terms (upper 1/5)

7. remaining 9 types of epithelial tissue 1. name drawingdescription fxn location

8. always has 1 free surface basement membrane on underside of ET; anchors it to the connective tissue below non-living layer of extracellular matrix

9. ET usually lacks blood vessels (avascular) cells readily divide cells tightly packed 4 fxn: 1. covers organs 2. forms lining of inner body cavities 3. lines hollow organs 4. may secrete, absorb, excrete substances

10. classified according to: shape and # layers of cells Shapes: 1. squamous- thin, flattened cells 2. cuboidal- cube-shaped cells 3. columnar- thin, elongated cells # layers: 1. simple- 1 layer of cells 2. stratified- 2 or more layers of cells

19. makes up glands 2 types: 1. exocrine- gland secretes products into ducts that open onto surface 2. endocrine- glands that secrete products into blood or fluids

20. use info on board

21. loose connective tissue aka areolar
