FINAL EXAM STUDY Flashcards
what is epithelial tissue made of
Epithelial tissue is made mostly of
cells with minimal amounts of
extracellular material
is epithelial tissue vascular or avascular
avascular but innervated
is epthelial tissue regenerative
yes highly which is good as often damaged
what is the basal lamina
Noncellular sheet made of
proteins
* Functions * Selective filter * Scaffolding for new, migrating
epithelial cells
what is the basement membrane made of
basal lamnia and reticular fibers
what are microvili
Folds of plasma membrane * Increase surface area to
increase absorption or
secretion
* Don’t move; smaller than cilia
what are cilia
Whip
-like, highly motile
extensions of plasma
membrane
* Moves fluid/substances in one
direction
what is celiac
Genetic autoimmune disease
* Body attacks and destroys the villi and
microvilli of the small intestine in
response to gluten
* Nutrients are not absorbed well
what is an example of an epithelium that protects
skin
what is an example of an epithelium that secretes
glands
what is an example of an epithelium that absorbs
small intestine
what is an example of an epithelium that diffuses
kidney
what is an example of an epithelium that filters
kidney
where is simple squamous found
diffusion in LUNGS
filtration in KIDNEY
secretion in SEROUS MEMBRANE
where is simple cuboidal found
absorption in KIDNEY
secretion in GLANDS
where is simple columnar found
absorption in GI
movement in BRONCHI
secretion of mucus
where is pseudostratified found
mucus in respirory tract
stratified squamous is found where
Protection: epidermis of skin
(keratinized); oral cavity and
esophagus (nonkeratinized)
stratified cuboidal is what
- Two layers of cube-shaped
cells - Protection and secretion:
salivary glands
where is stratified cuboidal found
protection in MALE URETHRA
some ducts and glands
where is transitional epithelium
in bladder
what is Membranous
- Membranous: majority of body coverings and linings (our focus)
what is Glandular
Glandular: specialized epithelial tissue that produces glandular secretions
difference between glandular and membranous
