Epithelial Tissue has closely packed cells, no blood supply and a high mitotic rate 3. The 3 surfaces of epithelial cells are the apical (free), lateral and basal 4. The basal surface is connected to a basement membrane 5. Epithelial cells are used for protection, absorption and secretion 6. Cell shapes found in epithelial tissue are squamous, cuboidal, columnar and transitional 7. The cells can be in a simple arrangement or a stratified arrangement 8. Cillia are longer projections used for movement of substances while microvilli are shorter projections used for absorption 9. Goblet cells secrete substances 10. Keratin is a protective protein that covers stratified squamous epithelium 11. The nucleus is in the center of squamous and cuboidal cells but at the base of columnar cells 12. Pseudo- means fake or false; pseudostratified means it looks like more than one layer but there is only 1 13. The 2 types of epithelial tissue are covering & lining AND glandular 14.To name an epithelial tissue you first name the arrangement (simple or stratified) then the shape (squamous, cuboidal or columnar) 15. When naming stratified tissue, the top layer of cells is used when determining the shape 16. Stratified cuboidal and stratified columnar are extremely rare 17. Simple Squamous is found in places that diffusion takes place (lungs) 18. Simple cuboidal and columnar are found where secretion and absorption take place (GI tract, respiratory tract) 19. Stratified Squamous is found in places with a lot of wear and tear (skin) 20. Columnar cells are the only cells that can be pseudostratified >ЦS Х Ц ·є·є·ЁCJ OJQJ^J 5БCJ\Б=>ХЦхц fg├─  ЛМп░ bc╤╥в¤√√√∙∙√√√√√√√√√√√√√√√√√√√√√√√Ц ■вг  D E П Р   R S Ц ¤¤¤¤¤¤¤¤¤¤¤√ 1Рh░╨/ ░р=!░Т"░8#Р$Р╨%░ i8@ё 8 NormalCJ_HaJmH sH tH <A@Є б< Default Paragraph Font<B@Є< Body Text5БCJ,OJQJ\Б^J>>@> Title$a$5Б>*CJ,OJQJ\Б^JFPF Body Text 25Б6БCJ,OJQJ\Б]Б^JЦ    =>ХЦхц fg├─  ЛМп░ bc╤╥вгDEПРRSШШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААШ0ААЪ0ААЦ вЦ  Ц ХЭЯзT^ыє$,19ДФВКМФPXЫгЕХШШ3<=>>ФХЦЦфхцц  ef┬├  kkКЛоп■ ab╨╤╓╫бв CDОПQRWХШ  Compaq Customer MC:\WINDOWS\Application Data\Microsoft\Word\AutoRecovery save of Document1.asdCompaq Customer cH:\2005-2006\Anatomy and Physiology\Topic 2 - Cells, Tissues and Tumors\Top 20 Epithelial Facts.doc!Lancaster Central School DistrictcH:\2005-2006\Anatomy and Physiology\Topic 2 - Cells, Tissues and Tumors\Top 20 Epithelial Facts.doc!Lancaster Central School DistrictxC:\Documents and Settings\Administrator\Application Data\Microsoft\Word\AutoRecovery save of Top 20 Epithelial Facts.asd @Ц`@  Unknown            GРЗz А Times New Roman5РАSymbol3&Р Зz А Arial5&Р ЗzaА Tahoma"qИЁ╨hQbЬ& 2▓Fў1▓Fєn С#ЁТ┤┤ББ20л2ГЁ  Top 20 Epithelial FactsCompaq Customer !Lancaster Central School District■ рЕЯЄ∙OhлС+'│┘0╕Ша└╠шЇ @L h t А МШаи░фTop 20 Epithelial Factsop Compaq Customer Faompomp Normal.doto"Lancaster Central School Districtos5ncMicrosoft Word 9.0c@xA╦@ъ╖юI╟@Ц[╖& ┼@Jь>ЁI╟єn■ ╒═╒Ь.УЧ+,∙о0 hp|ДМФ Ьдм┤ ╝ рф0 л Top 20 Epithelial Facts Title ■    ■   ■    !"■   ¤   %■   ■   ■                                                                                                                                                                                                                                                                                                                                                                   Root Entry         └F@ПйVЁI╟'А1Table             WordDocument        "SummaryInformation(    DocumentSummaryInformation8            CompObj    jObjectPool            @ПйVЁI╟@ПйVЁI╟            ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■       └FMicrosoft Word Document MSWordDocWord.Document.8Ї9▓q
