EPITHELIAL Flashcards
Classification of Epithelial Tissue - Number of Cell Layers?
Simple - One Layer
Stratified - More Than One Layer
Classification of Epithelial Tissue - Shape of Cells?
Squamous - flattened
Cuboidal - cube shaped
Columnar - column like
Pseudo stratified - goblet shaped
Simple Squamous has how many layers ?
One single flat layer of cells.
Simple Squamous is where?
Usually forms in Membranes.
Lines Body Cavities
Such as Lungs and Capillaries
Simple Cuboidal has how many layers?
Single Layer that is Cube-Like Cells.
Where is Simple Cuboidal Located?
Common in glands and their ducts.
Forms on walls of Kidney Tubules and covers the Ovaries
How many layers does Simple Columnar have?
One single Layer of Tall Cells
Where is Simple Columnar Located?
-includes mucus - producing Goblet cells.
Lines Digestive Tract
How many layers does Pseudo Stratified Columnar have?
A single Layer, but some cells are shorter than others.
Often look like a double layer of cells.
Where are Pseudostratified cells located?
Sometimes Ciliated, such as in the Respiratory Tract
May Function in Absorption or Secretion.
Describe Stratified Epithelia (layered.)
Cells at the apical surface are flattened.
Is seen as a protective covering where friction is common.
Where is Stratified Epithelia located?
Skin
Mouth
Esophagus
How many layers does Stratified Cuboidal have?
Two Layers of cuboidal cells
Stratified Columnar, Describe it?
Surface cells are Columnar, Cells underneath Vary in size and shape.
Stratified Cuboidal and Columnar, describe?
RARE in human Body
Found mainly in ducts of large glands.
