Simple cuboidal epithelium                    Chart


Differential diagnosis:
ther epithelium types such as squamous and columnar epithelium. Note that such epithelia have cells which are either flat (squamous) or very tall (columnar). Transitional epithelia 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 or compact
b. Consists of cells which are as tall as they are wide; i.e. isodiametric.
c. One cell layer on top of basement membrane.
d. Make certain that epithelium is being examined and not the connective tissue below it under the basement membrane.
Examples include the collecting duct of the kidney and thyroid follicular cells.

Database selection: Practical Tissue Gross

Level 1: Select hollow
Level 2: Select epithelial tissue from list of sclerous, muscular, connective organ-glands and nervous tissues
Level 3: Select simple since only one cell layer can be seen on basement membrane
Level 4: Select cuboidal since all cells are isodiametric; i.e they are as tall as they are wide.

Do you think this is a section of the collecting duct of the kidney?
