Basic Histology -- Simple Cuboidal Epithelium Next Home Back

All body surfaces except the teeth and the gliding surfaces of joints are normally covered with epithelium.

Epithelium is tightly-joined cells on top of a layer of collagen (the "basement membrane") which marks its border with connective tissue.

This extends to the tiny surfaces of glands. Even the glands whose ducts are lost during embryonic life (i.e., the endocrine glands) have epithelium as their business cells.

Here is how to name a surface epithlium:

The most elementary epithelium is "simple cuboidal".

This is a cluster of ducts in the pancreas. You can see the cell borders easily here.

Don't worry about what's at the far right -- it's a curious little type of duct slipping into a secretory unit.

With your study partners, find:

Hotshots: We think that too much attention goes to memorizing where you're supposed to see "tall cuboidal" vs. "low columnar".

You do need to know:

The presence of contractile myoepithelium as a second layer around the epithelium does not turn simple into stratified.
