A sheet of cells covering external and lining internal body surfaces.

Protection against wear, hydration, and dehydration; regulates substance movement.

One layer of cells.

Multiple layers of cells.

Flat, irregular, thin cells.

Epithelial cells constantly regenerate.

Cells have distinct apical, lateral, and basal surfaces with specialized functions.

The way epithelial cells attach to their neighbours or basement membrane.

Appears layered but all cells touch the basement membrane, containing both tall and short cells; may be ciliated or non-ciliated.

Pseudostratified epithelium with cilia and goblet cells, lining parts of the respiratory tract, secretes mucus, and moves it out.

Multiple layers of cells with flattened, superficial cells; protects underlying tissues. Can be keratinized(dry) or non-keratinized(wet).

Stratified squamous epithelium without keratin, found in moist areas, nuclei present in the surface cells. Example: lining of the esophagus

Stratified squamous epithelium lacking nuclei in the top layer due to keratin; forms a tough protective barrier. Example: skin.

Epithelium that changes shape in response to stretching. Relaxed state has cuboidal cells and stretched is squamous cells; found in the urinary tract.

The deepest layer of stratified epithelium cells. This layer is constantly dividing.

A thin layer that separates the epithelium from underlying connective tissue. All cells rest on this membrane

Thin, flat cells forming a single layer, found lining blood vessels, alveoli, and Bowman's capsule. It's part of the endothelium and mesothelium, and is non-specialized, renewing through mitosis.

Cells resemble cubes, with a central nucleus. Primarily associated with absorption, found in glands and kidney tubules.

Found lining kidney tubules and thyroid follicles.

Lines the gastrointestinal tract (GIT), for absorption and secretion.

Tall, column-shaped cells with nuclei toward the base and often microvilli on the apical surface. Specialized for absorbing nutrients.

Column-shaped cells with cilia for movement (e.g., mucus in the respiratory tract).

Epithelium in the gut lining, featuring distinctive features like microvilli and goblet cells for increased absorption and secretion.

Epithelial cells can renew via either mitosis (non-specialized) or stem cells (specialized).
