| Characteristics of Epithelial Tissue |
|
Definition
- Mostly a covering/lining or a gland
- Mostly cells, little extracellular material
- Apical/free surface and basal surface
- Basement membrane - secreted by tissue made of protein/carb

|
|
Term
|
Definition
| Multiple layers of cells, but only one basal layer attached to basement membrane. |
|
|
Term
|
Definition
| Bottom layer of epithelium that is attached to the basement membrane. |
|
|
Term
|
Definition
| Special protein/carbohydrate secretion of epithelial tissues that attaches it to other tissue types. |
|
|
Term
| Pseudostratified columnar epithelium |
|
Definition
| A type of simple epithelium that appears to be stratified, but is not. Consists of one layer of cells that are all attached to the basement membrane, but not all extend to the free surface. |
|
|
Term
|
Definition
| Special columnar cells found in digestive and respiratory system that produce mucous. |
|
|
Term
| Simple Columnar Epithelium |
|
Definition
- Single layer of tall narrow cells.
- Important in movement of materials.
- Some cells have cilia or microvilli.
- Contain goblet cells.
|

Term
| Four types of cell connections |
|
Definition
Desmosomes
Hemidesmosomes
Tight Junctions
Gap Junctions |
|
|
Term
|
Definition
| Attach cells together using glycoproteins and carbs secreted by epithelial cells. Add strength. |
|
|
Term
|
Definition
| Glycoproteins used to attach epithelial cells to the basement membrane. |
|
|
Term
|
Definition
| Glycoproteins that act to waterproof the cell membranes in areas that remain watertight and act as a barrier between cells. |
|
|
Term
|
Definition
| Protein channels that directly link cells, which aids in communication. |

Term
| Function of microvilli on cell surface |
|
Definition
| Increase surface area for absorption or secretion. |

Term
| Function of cilia on cell surface |
|
Definition
| Movement of materials across the cell surface. Found throughout the respiratory system. |

Term
| Function of folds on cell surface |
|
Definition
| Allow transitional epithelium to change shape. Found in urinary system. |
|
|
Term
|
Definition
| Stratified cells that appear cuboidal when organ or tube is not stretched and squamous when organ or tube is stretched by fluid. |
