BIO 204: Chapter 5 Tissues
1. tissues: groups of cells similar in structure and function
2. histology: study of tissues
3. 4 types of tissues: epithelial, connective, muscle, nerve
4. nervous tissue is responsible for: internal communication
5. where is nervous tissue found: brain, spinal cord, nerves
6. muscle tissue is responsible for: contracting to cause movement
7. where is muscle tissue found: muscles attached to bones, heart, walls of hollow organs
8. epithelial tissues is responsible for: forming boundaries between different environments; protect-
ing, secreting, absorbing, filtering
9. where is epithelial tissue found: lining of digestive tract organs and other hollow organs, skin surface
10. connective tissue is responsible for: supporting, protecting, binding other tissues together
1/8
,11. connective tissue is found in: bones, tendons, fat, and other soft padding tissue
12. 2 main types of epithelial tissue: covering and lining epithelium, glandular epithelium
13. where is covering and lining epithelium found: external and internal surfaces
14. example of covering and lining epithelium: skin
15. where is glandular epithelium found: secretory tissue in glands
16. example of glandular epithelium: salivary glands
17. functions of epithelium: protection, filtration, absorption, excretion, secretion
18. characteristics of epithelial tissues: polarity, specialized contacts, supported by connective tissues,
avascular but innervated, can regenerate
19. how does epithelium exhibit polarity?: by having an apical surface and a basal surface
20. special contacts: cells form continuous sheets held together by tight junctions and desmosomes
21. cellularity: composed almost entirely of cells
2/8
, 22. explain what avascular but innervated means: doesn't have its own blood supply but has
nerve supply
23. what does regenerative mean: ability to replace lost or damaged cells
24. how is epithelium classified: by number of layers and by cell shape
25. how many layers does simple epithelium have: one cell layer
26. how many layers does stratified epithelium have: multiple cell layers
27. how many layers does pseudostratified epithelium have: one but it gives the false
impression of multiple layers
28. squamous cells: flattened cells
