Epithelial Tissues Flashcards
squamous shape
flat
4 examples of sites with simple squamous epithelium
alveoli, capillaries, and inner lining of blood vessels, and membranes
basement membrane is made of ____ tissue
nonliving
3 modes of secretion
merocrine, apocrine, and holocrine
spherical cells with central nuclei
simple cuboidal
some have cilia, ex: in uterine tube
simple columnar
examples of compound multicelled branches of glandular epithelium
complex ducts
which cells have access to nutrients in stratified squamous?
the lower layer of reproducing cells
desmosomes
single areas of connection
main function of stratified squamous
protection
cuboidal shape
square/cube
tissue that is more stretchable and can change shapes
transitional epithelium
examples of locations of exocrine glands
intestinal tract and skin
cells that produce and secrete substances
glandular epithelium
thick layer, outermost flat
stratified squamous
goblet cell function
secretes protective mucous
gap junctions
channels which allow molecules to move between cells (also some signal conduction)
3 types of intercellular junctions
tight junctions, desmosomes, and gap junctions
columnar shape
tall/rectangular
epithelial tissue is made up of ____ dividing cells
rapidly
not a protective layer of tissue
simple squamous epithelium
3 shapes of cells
squamous, cuboidal, and columnar
purpose of goblet cells in pseudostratified columnar
secrete a protective layer of mucous in the respiratory tract and help to move and dispel of particles
the skin cells on the top layer of the surface are ___ due to having no access to ___
dead, nutrients
holocrine gland examples
Sebaceous glands of the skin
apocrine gland examples
Mammary glands, ceruminous glands lining the external acoustic meatus
endocrine
secrete into blood or tissues
tissue that is easy to pass through
simple squamous epithelium
2 locations where transitional epithelium is found
ureters and urinary bladder
2 classifications of epithelium
thickness of tissue layer and shape of cells
involved in secretion and absorption
simple cuboidal
