Stem cells |
Actively dividing cells.... Cells that keeps dividing |
|
|
Stem cells can rise to four main tissue groups. What are they? |
Epithelial tissue, connective tissue, muscle tissue, nervous tissue. |
|
|
Epithelial tissue |
Tissue covers surfaces, lines cavities, and forms glands. forms a protective covering for the body it is the main tissue of the skins outer layer. |
|
|
Connective tissue |
Supports informs the framework of all parts of body |
|
|
Muscle tissue |
Contracts and produces movement. |
|
|
Nervous tissue |
Conducts nerves impulses |
|
|
Which two main tissue group form then sheets of tissue |
Epithelial tissue and connected tissues |
|
|
Epithelial forms what? |
Membranes, ducts, In the lining of the body cavities and hollow organs such as the organs of the digestive, respiratory, urinary tract. |
|
|
Can Apple Billiem repair it so quickly after it is injured |
Yes in areas of the body subject to normal wear and tear such as skin, the inside of the mouth, and the lining of the intestinal track |
|
|
Structure of epithelial tissue |
Epithelial cells are tightly packed to better protect underlying tissue or form barriers between systems the sales very in shape in arrangement according to their functions. |
|
|
Epithelial cells very in shape what are the shapes? |
Squamous Cuboidal Columnar |
|
|
Squamous |
Flat and irregular |
|
|
Cuboidal |
Square |
|
|
Columnar |
Long and narrow |
|
|
Nervous tissue and muscle tissue maintain few |
Have few Stem cells that divide infrequently so the tissue repairs slowly if at all |
|
|
Epithelial tissue also forms a |
Duct,membranes ,and the lining of the body cavities,and Hollow organs, such as digestive, respiratory, and urinary tracts |
|
|
How can epithelial tissue be described? |
By the shape of the cell |
|
|
Layers of epithelial tissue |
Simple- Single layer Stratified -multiple layers Pseudo stratified-sales are staggered so they appear to be multiple layers but really were not
Simple squamous epithelial -single layer of flat , irregular cells Stratified squamous epithelium |
