|
epithelial tissue; epithelium
|
the lining, covering, and glandular tissue of the body
Functions: protection, absorption, filtration and secretion have no blood supply: avascular |
|
|
apical surface
|
surface of a tissue that is exposed to the body's exterior or to the cavity of an internal organ
|
|
|
basement membrane
|
the lower surface of a tissue, a structureless material secreted by cells
|
|
|
avascular
|
tissues that have no blood supply
|
|
|
simple tissue
|
one layer of cells
|
|
|
stratified tissue
|
more than one layer of cells
|
|
|
squamous cells
|
flattened like fish scales
|
|
|
cubital cells
|
cube-shaped
|
|
|
columnar cells
|
shaped like columns
|
|
|
simple squamous epithelium
|
single layer of thin squamous cells resting on a basement membrane
forms membranes where filtration or exchange of substanecs by rapid diffusion occurs. (ie. air sac in lungs, forms walls of capillaries, form serous membranes or serosae)ser |
|
|
serous membranes; serosae
|
the slick membranes that line the ventral body cavity and cover the organs in that cavity
|
|
|
simple cuboidal epithelium
|
one layer of cuboidal cells resting on the basement membrane
-common in glands and their ducts -salivary glands and pancreas, walls of kidney tubules and covers surface of ovaries |
|
|
simple columnar epithelium
|
made up of single layer of tall cells that fit closely together
-goblet cells -lines entire length of the digestive tract from the stomach to the anus -mucus membranes |
|
|
goblet cells
|
produce a lubricating mucus, in in simple columnar epithelium
|
|
|
mucous membranes; mucosae
|
epithelial membranes that line the body cavities open to the body exterior
|
|
|
psuedostratified columnar epithelium
|
rest on basement membrane, some of the cells shorter than others and their nuclei appear at different heights above basement membrane-give false (psuedo) impression that it is stratified
-main functions in absorption and secretion -mucous produces by goblet cells traps dust/debris, cilia propel mucus upward and away from the lungs |
|
|
psuedostratified ciliated columnar epithelium
|
lines most of the respiratory tract
|
|
|
stratified squamous epithelium
|
consists of several layers of cells
-cells that are free edge are squamous cells, cells close to basement membrane are cuboidal or columnar -most common stratified epithelium in body -found in sited that receive a good deal of abuse or friction (esophagus, mouth, outer portion of skin) |
|
|
stratified cuboidal
|
typically has just two cell layers with (at least) the surface cells being cuboidal in shape
-rare in body, found mainly in ducts and large glands |
|
|
stratified columnar
|
surface cells columnar cells, basal cells vary in size and shape
-rare in body, found in mainly ducts and large glands |
|
|
transitional epithelium
|
highly modified, stratified squamous epithelium
-forms lining of only a few organs, bladder, uterers and parts of urethra (in urinary system) -basal layer cells are cuboidal or columnar, cells at free surface vary in appearance -change shape, ureter wall rounded to squamous cells change from being rounded to squamous |
