Polarity, specialized contacts, supported by connective tissues, a vascular innervated (yes nerves, no blood vessels), regeneration
Squamous
Flat
Simple
1 layer
What is simple good for?
Absorption, diffusion
Simple Squamous is good for
Rapid diffusion
Simple Columnar
Microvilli, more cytoplasm
Pseudostratified Columnar
1 layer, nuclei not lined up
Stratified Squamous
protects underlying tissues from abrasion
Transitional Epithelium
Stratified, have ability to stretch then flatten
