Stratified squamous epithelium             Chart    


Differential diagnosis:
Other epithelium types such as cuboidal and columnar epithelia. Note that such epithelia have cells which are either flat (squamous) or very tall (columnar). Transitional epithelium have cuboidal shaped cells on top when there is no distension as in urinary bladder. The transitional epithelium however is never simple (i.e. one layer thick) and it has  more than one shape of cells lying on the basement membrane.		 Roll over mouse

Diagnostic Features:
a. Tissue may be hollow (oesophagus)
b. Consists of cells which are flattened pavement polyhedral cells.
c. They are more than one cell layer on top of the basement membrane; hence stratified.

Database selection: Tissue Gross

Lesson

Level 1: Select hollow
Level 2: Select epithelial tissue from list of sclerous, muscular, connective organ-glands and nervous tissues
Level 3: Select stratified since only one cell layer can be seen on basement membrane
Level 4: Select squamous since all cells are taller than they are wide.

Do you think this is a section of the vagina, esophagus, mouth, cornea (anterior surface), lower part of pharynx or parts of the cervix uteri?
