Epithelial tissue |
A sheet of cells that covers a body surface or lines a body cavity |
|
|
Apical surface |
An upper free surface exposed to the body exterior or the cavity of a internal organ |
|
|
Basal surface |
Bottom edge of the cell or tissue |
|
|
Microvilli |
Finger like extensions of the plasma membrane |
|
|
Basal lamina |
Acts as a filter, sits next to the basal surface |
|
|
Reticular lamina |
A layer of extracellular material containing a layer of colagen protein fibers |
|
|
Basement membrane |
Reinforces the epithelial tissue helps it resist stretching and tearing and defines the epithelial boundary |
|
|
Simple epithilial |
Consists of a single cell layer that are typically found where absorption secretion and filtration occur and a thin epithelial barrier is desirable |
|
|
Stratified epithelial |
Composed of two or more cell layers stacked on top of each other are common and high abrasion areas or protection is important such as the skin surface and the lining of the mouth |
|
|
Simple squamous epithelium |
Flattened laterally. And their cytoplasm is sparse. found where filtration or the exchange of substances by rapid diffusion is a priority in the Kidneys it forms part of the filtration membrane in the lungs that forms the walls of the air sacs |
