Epithelium
- According to cell arrangement: sheet (membranous), trabecular, reticular
- According to a function: covering, secretory, absorptive, respiratory and
sensory + myoepithelial cells
- Covering epithelium - classification
Covering epithelium - classification
Simple
 Simple squamous
 Simple cuboidal
 Simple columnar
 Pseudostratified
columnar
- According to the number of cell layers and shape of cells in the
most superficial layer
Stratified
 Stratified squamous
 Stratified squamous
keratinized
 Stratified columnar
 Transitional
