Hard to see, but after a small gap at the tip of the pointer there is a specialized feature to these Simple Columnar Epithelium cells

What is it?

What do these types of cells specialize in?

Where are they found?

Cilia. (This is a Ciliated Simple Columnar Epithelium cell.)
They specialize in secretion and some absorption.
They are found in Uterine Tubes, Fallopian Tubes, or the Upper Respiratory Tract.

Hard to see, but what type of Epithelia is this? (Hint: The nuclei are all along the basement membrane)

Name:

Function:

Location:

Any Specialized Structures:

Simple Columnar Epithelium (non-ciliated)
Found in the lining of the Stomach and Intestines, some Salivary Glands, Gall Bladder
Function is Secretion and some Absorption
Specialized Structures are Goblet Cells (which are visible and should give away what type of epithelium this is)

Name:

Function:

Locatioin:

Any visible specialized structures:

Psuedostratified Columnar Epithelium (Nuclei scattered between top and bottom of cell)
Function is Secretion or Absorption
Found in areas that need a little more durability; Upper Respiratory Tract, Eustachian Tubes
Visible Specialized Structure would be Cilia (easily visible at the top near the free surface)

Function:

Location:

Stratified Squamous Epithelium (notice how the cells get more and more flattened as they move towards the free surface)
Function is protection and coverings in areas of high abuse
Found the thickest in areas that are constantly being abused; Palms of your Hands or the Soles of your Feet (areas with skin or lining wet surfaces such as mouth, esophagus, and vagina)
