STUDY
PLAY
simple
a single layer of epithelial cells
stratified
two or more layers of epithelial cells
apical
stratified epithelia are classified according to the appearance of the cells at the ___ surface
squamous cuboidal columnar
list the three basic shapes of covering and lining epithelial tissues
squamous
___ cells are flattened and thier nuclei usually appear as flattened discs
cuboidal
____ cells are box-like and thier nuclei are usually sperical
columnar
____ cells are tall and column shaped with nuclei that are usually elongated top to bottom and are genearlly located close to the base of the cell
endothelial
simple squamous epithelials cells are called ___ cells
endothelial
cells that line the internal surfaces of blood vessels and the heart and/or form lymphatic vessels; classified as simple squamous
mesothelium
refers to the simple squamous epithelium present in serous membranes that line the ventral body cavity and cover the outer surface of the organs it surrounds
simple squamous
epithelim that has a single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm
simple squamous
epithelim that allows passage of materials by diffusion and filtration in sites where porection is not importana
simple squamous
epithelim that secretes lubricating substances in serosae
simple squamous
epithelium that is located in air sacs of lungs, lining of heart, blood vessels and lymphatic vessels and the lining of the ventral body cavity serosae
stratified squamous
epitheliumthat are thick membranes composed of several cell layers; basal cells are cuboidal or columnar and metabolically active; surface cells are squamous; basal cells are active in mitosis and produce the cells of the more superficial layers
keratinized
in the ____ type of stratified squamous epithelium, the surface cells are full of keratin and dead
stratified squamous
epithelium that protects underlying tissues in areas subjected to abrasion
stratifed squamous
epithelium that forms moist linings of the esophagus, mouth and vagina (nonkeratinized)
stratified squamous
epithelium that forms the epidermis of the skin (keratinized)
esophagus, mouth vagina skin
list 4 linings where stratified squamous epithelium are located
heart, blood vessels, lymphatic vessels, ventral body cavity, air sacs of lungs
list 5 linings where simple squamous epithelium are located
simple cuboidal
epithelium that has a single layer of cubelike cells with large, spherical central nuclei
simple cuboidal
epithelim that secretes and absorbs
simple cuboidal
epithelium that is located in the kidney tubules; ducts and secretory portions of small glands; ovary surface
kidney tubules, ducts, ovary surface
list 3 places simple cuboidal epithelium cells are located
stratified cuboidal
epithelium that is generally two layers of cubelike cells
stratified cuboidal
epithelium that serves as protection
stratified cuboidal
epithelium that is located in the largest ducts of the sweat glands, mammary glands and salivary glands
sweat, mammary, salivary
name three glands that stratified cuboidal epithelium form
simple columnar
epithelium that is a single layer of tall cells with oval nuclei; some have cillia; layer may contain mucus-secreting goblets
goblet
mucus-secreting unicellular glands
simple columnar
epithelium that absorb, secrete mucus, enzymes and other substances
ciliated simple columnar
epithelium that propel mucus or reporductive cells by ciliary action
simple columnar
epithelium that line most of the digestive tract (stomach to anal canal), gallbladder and excretory ducts of some glands
ciliated simple columnar
epithelium that line small bronchi, uterine tubes and some regions of the uterus
digestive tract, gallbladder, excretory ducts, small bronchi, uterine tubes
