clue: lack of distint layers
|
pseudostratified
|
|
- one layer
- beadshaped - fxn: secretion, absorption - loc: lines glands |
simple cuboidal
|
|
- one layer
- tall cells - usually contains goblet cells - fxn: absorption; secretion - loc: line digestive tract |
simple columnar
|
|
characteristic of epithelial tissue that is supplied by nerve fibers but lacks blood vessels?
|
innervated but avascular
|
|
- one layer
- varying heights - nuclei at different heights - cilia - fxn: secretion - loc: non- ciliated= line gland ducts ciliated= trachea/upper respiratory tract |
pseudostratified columnar
|
|
- one layer
- disc-shaped - fxn: rapid diffusion, filtration - loc: air sacs in lungs, kidney |
simple squamous
|
|
- many layers
- basal cells: cuboidal/columnar - apical cells: squamous - fxn: protection - loc: skin (ker.) mouth, lips, etc (non ker.) |
stratified squamous
|
|
characteristic of epithelial tissue that forms continuous sheets; many tight junctions and desmosomes?
|
specialized contacts
|
|
clue: only cuboidal at apical surface; only TWO cell layers
|
stratified cuboidal
|
|
Tissue made of sheets of cells that cover a body surface or line a body cavity
|
epithelial tissue
|
|
clue: only columnar at apical surface
|
stratified columnar
|
|
six characteristics of epithelial tissue
|
- cellularity
- specialized contacts - polarity - basement membrane - innervated but avascular - regeneration |
|
clue: cuboidal/columnar at apical surface- mixed up
|
transitional
|
|
characteristic of epithelial tissue that is the non-cellular adhesive sheets that act to filter substances and for reinforcement?
|
basement membrane
|
|
clue: only has squamous cells at apical surface
|
stratified squamous
|
|
characteristic of epithelial tissue that is when the cells replace themselves quickly by cell division?
|
regeneration
|
|
- resembles stratified squamous/cuboidal
- fxn: stretching, distention - loc: lines part of urethra, bladder, ureter |
transitional
|
|
characteristic of epithelial tissue that are when cells near the free surface of the tissue (apical surface) differ from the ones that are attached (basal surface)?
|
polarity
|
|
- several layers
- basal: cuboidal - apical: columnar - fxn: protection, secretion - loc: (rare) male urethra, some large ducts of glands |
stratified columnar
|
|
what is the characteristic that is composed almost entirely of closely packed cells?
|
cellularity
|
|
- only 2 layers
- fxn: protection - line large ducts of sweat, mammary, salivary glands... |
stratified cuboidal
