(41 cards)
_______ will always be present in epithelium
Basal lamina
What’s another name for basal lamina?
Basement membrane
__________ epithelium is found in organs where protection is needed by need things to pass through
Simple squamous
_____________ epithelium is present in blood vessels, kidney and lung
Simple squamous
____________ epithelium is a single layer of square shaped cells with round nuclei in the center of the cell
Simple cuboidal
_____________ epithelium is seen in the thyroid gland, kidney
Simple cuboidal
_________ are types of cells primarily found in the digestive system and are long rectangles
Simple columnar
When you see columnar in the name, what is it important to look for?
Cilia
How does someone identify the epithelium that have multiple layers?
Go to the lumen and look at the first layer of cells
______________ have multiple layers of cells but the top layer of cells do not have nuclei
Stratified squamous; keratinized
____________ has two layers of cuboidal cells
Stratified cuboidal
Where do you go when you need to identity stratified columnar epithelium?
Lumen and look to see if see a rectangular shape
In _________ epithelium every cell roughed the basement membrane but not all of the cells reach the luminal surface
Ciliated or noncililated pseudostratified columnar epithelium
___________ looks like stratified cuboidal epithelium but will always have more than 2 layers of cells and have a scalloped luminal surface
Transitional epithelium
__________ seals neighboring cells together in an epthelial sheet to prevent leakage of molecules between them
Tight junction
__________ joins an actin bundle in one cell to a similar bundle in a neighboring cell
Adherns junction
________ joins the intermediate filaments in one cell to those in a neighbor
Desmosome
_____________ allows the passage of small water-soluble ions and molecules
Gap junctions
__________ anchors intermediate filaments in a cell to the basal lamina
Hemidesmosome
___________ can be classified as unicellular or multicellular
Glandular units of glandular epithelium
_________ cells are examples of unicellular glandular units
Goblet cells
__________ are examples of multicellular glandular units
Salivary glands
How do you classify if a glandular unit is multicellular vs unicellular?
The number of cells that are in the secretory unit if one cell then unicellular if multipleunits then multicellular
__________ glands are those that secrete a secretory solution at a remote site and then deliver it to its target through a duct
Exocrine
