DESCRIPTION: Single layer of cells of differing heights, some not reaching the free surface; nuclei seen at diff levels; may contain mucus-secreting cells & bear cilia.
Has ciliated and nonciliated for, is simple epithelial w/ false appearance of stratification. Ciliated pseudo columnar is referred to as resp epithelium(is endowed w/ goblet cell which secrete mucus away from lungs)
FUNCTION: Secretion, particularly of mucus; propulsion of mucus by ciliary action
LOCATION: Nonciliated pseudo is found in male's sperm-carrying ducts (vasa deferentia, epididymides ejaculatory ducts, urethra) and ducts of large glands, ciliated variety lines the trachea, most of upper resp tract. Cilia beat to create a undirectional current that moves mucus away from lungs and into pharynx,
