Flashcards in Types of Epithelium Deck (24)
What type of tissue has stratified cuboidal or columnar epitthelium?
What type of tissue has stratified sqaumous keratinized epithelium?
What type of tissue has stratified sqaumous non keratinized epithelium?
What type of tissue has simple squamous epithelium?
What type of tissue has simple cuboidal epithelium? also knowns as what kind of layer?
RPE (dont forget pigmentation, thyroid and kindey also have it)
Pseudostratified columnar cells are found in what tissue? key characteristic?
Respiratory (i.e. trachea) signature cilia
SImple columnar epithelium found where?
Transitional epithelium found where? what is so unique about it?
sizing of cells, apical has large cells and basal is smaller this is normally the opposite in this tissue.
Avg radius of globe?
Avg radius of cornea?
Avg width of central cornea?
Avg width of peripheral cornea?
BM is about how thick?
Bowmans is how thick?
decemets is how thick? does it remain this thick throughout life? what is unique about decemets?
no it gets thicker with age
it has NO hemidesmosomes
can the bowmans membrane regenerate if damaged? can decemets?
NO leaves a scar.
Can corneal epithelium regenerate? can corneal endothelium?
yes as long as bowmans is not damaged, yes.
corneal epithelium is normally how many cell layers thick? what types of cells?
basal cells (one layer)
Wing cells (2-3 layers)
Superficial cells (2-3 layers)
what tissue has dense irregular tissue?
dermis of skin, glands
what tissue has dense irregular CT?
corneal stroma and sclera
what tissue has loose CT?
What type of structure are the sweat glands?
simple coiled tubular
what type of structure are the oil glands?
simple branched acinar
