- epithelial tissue
- protects blood vessles and organs
- is supported by a basement membrane and can consist of simple and stratified layer of cells
- simple- one layer
- stratified- multiple layers
- they are classified into shapes:
- squamous: flat and scale like
- simple: so thin that is offer s no protection. its function allows materials to pass through
- stratified: is usuallly made up of many layers of cells that it offers the best protection to the blood vessles or organs underneath
- cuboidal: tall as they are wide
- simple: offers some protection but it more prevalent when materials must be secreted or absorbed.
- stratified: typically only found in areas where secretion os importantbut where a little more protection is needed than just simple cuboidal
- columnar: tall and column shaped
- simple: offers some protectioon of underlying tissue. it's found in places where protection is nessary and where secretion occurs
- stratified: these are rare and are found in places requiring ultimate protection and where secretion occurs
- squamous: flat and scale like
- characteristics
- they have one basal section
- nutrients are from the baement membrane as they lack blood vessels
- they are sensory
- fix themselves through mitosis
- can have cilia or microvilli
- compacted tightly together in one layer
