consists of a single layer of cells, with each cell extending from the basement membrane to the free surface
consists of more than one layer of cells, but only the basal layer attaches the deepest layer to the basement membrane
pseudostratified columnar epithelium
special type of simple epithelium that appears to be stratified but is not
nonkeratinized stratified squamous epithelium
stratified squamous epithelium that consists of living cells in the deepest and outermost layers; layer of fluid covers the outermost layers; found in areas such as the mouth, esophagus, rectum and vagina
keratinized stratified squamous epithelium
stratified squamous epithelium that consists of liveing cells in the deepest layers and dead cells in the outermost layers; dry, durable, moisture-resistant character; found in the skin, gums and oral hard palate
stratified epithelium where the shape of the cells and number of cell layer vary; underlying cells are roughly cuboidal or columnar when not stretched and become more squamous when they are stretched; lines the urinary bladder, ureters, pelvis of the kidney and the superior portion of the urethra
elongated microvilli found in sensory organs, such as the inner ear; play a role in sound detection
disk-shaped structure with especially adhesive glycoproteins that bind cells to one another and intermediate filaments that extend into the cytoplasm of the cells
holds cells together and forms a permeability membrane; formed by plasma membranes of adjacent cells that join to one another in a jigsaw fashion
located between the plasma membranes of adjacent cells and just below the tight junction; acts as a weak glue that holds cells together
small, specialized contact region between cells containing protein channels that aid intercellular communication by allowing ions and small molecules to pass from one cell to another
secretory organ; composed primarily of epithelial cells supported by a connective tissue network; develop from an infolding or outfolding of epithelium
