Presentation Transcript

  1. Anatomy 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. 4 major types of tissues: • 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. Epithelial Tissue • 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 drawing description fxn location

  8. Epithelial Tissues • 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: • covers organs • forms lining of inner body cavities • lines hollow organs • 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

  11. Simple Squamous Epithelium

  12. Simple Cuboidal Epithelium

  13. Simple Columnar Epithelium

  14. Pseudostratified Columnar Epithelium

  15. Stratified Squamous Epithelium

  16. Stratified Cuboidal Epitelium

  17. Stratified Columnar

  18. Transitional Epithelium

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

  20. Connective Tissues Foldable • use info on board

  21. Connective Tissues Catalog • loose connective tissue • aka areolar

  22. adipose tissue aka fat

  23. Dense Connective

  24. Cartilage- hyaline

  25. cartilage- elastic

  26. cartilage- fibrocartilage

  27. Bone

  28. Blood

  29. Skeletal Muscle Tissue

  30. Smooth Muscle Tissue

  31. Cardiac Muscle Tissue
