Location of Epithelial Tissue

Simple squamous

location: alveoli and lining of the blood vessels

Nucleus is centrally located

Simple cuboidal

location: kidney tubules

Ciliated simple columnar

location: oviducts/upper respiratory tract

Nonciliated simple columnar

location: Ileum, gallbladder and urinary tract

may contain goblet cells (secrete mucus)

Simple Columnar with microvilli brush border

location: duodenum

microvilli found at apical surface to increase surface area

Keratinized stratified squamous

location: superficial skin layer

contains filaments of the protein keratin, cells accumulate keratin as they age become tough and water resistant

Non-keratinized stratified squamous

location: esophagus, oral cavity, vagina, anal canal

no keratin, must be kept moist

Stratified Cuboidal

location: ducts of mammary sweat and salivary glands

Stratified columnar

location: lining of developing ovarian follicles

rare

Ciliated pseudostratified Columnar Cilia = movement of materials

location: respiratory passages

only a single layer but nuclei are at different levels and not all cells reach the free surface

Nonciliated pseudostratified Columnar epithelium

location: prostate, vas deferens

No mucus or cilia

Transitional

location: Urinary bladder
