Unformatted text preview: columnar epithelial cells have microvilli to increase surface area for absorption Uterine tubes – simple columnar epithelial cells have cilia that help move the egg to the uterus Central canal of spinal cord – ciliated cells move cerebrospinal fluid Stratified Squamous Epithelia Surface of skin (keratinized stratified squamous epithelium) – epithelial layer of skin is a tough, dry, waterproof outer surface that form a protective barrier Lining of mouth, esophagus, anus, and vagina (non-keratinized stratified squamous epithelium) – moist epithelial layer that forms a protective barrier in areas subject to abrasion and friction Transitional Epithelia Lining of urinary bladder and parts of the ureters and the urethra – provides a protective barrier that permits distension Pseudostratified Columnar Epithelia Lining of nasal cavity, trachea, and bronchi – secretion of mucus by goblet cells. The columnar cells have cilia which move mucus toward the pharynx....
